1998/99 ACM International Collegiate Programming Contest University of Ulm Local Contest Problem G Goldbach's Conjecture Input file: goldbach.in In 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture: Every even number greater than 4 can be written as the sum of two odd prime numbers. For example: 8 = 3 + 5. Both 3 and 5 are odd prime numbers. Today it is still unproven whether the conjecture is right. (Oh wait, I have the proof of course, but it is too long to write it on the margin of this page.) Anyway, your task is now to verify Goldbach's conjecture for all even numbers less than a million. Input Specification The input file will contain one or more test cases. Each test case consists of one even integer n with Input will be terminated by a value of for n Output Specification For each test case, print one line of the form n = a + b , where a and b are odd primes. Numbers and operators should be separated by exactly one blank like in the sample output below. If there is more than one pair of odd primes adding up to n , choose the pair where the difference b - a is maximized. If there is no such pair, print a line saying "Goldbach's conjecture is wrong."

Sometimes that means having company desktops locked down and administrative rights to laptops restricted so people cannot install unapproved software on the network.

Evenly divisible only by themselves and one, primes are a rich source of speculative ideas that mathematicians often find simple to state but difficult to prove. The Goldbach conjecture is a prime example of such a conundrum. In a letter written in 1742 to Leonhard Euler (1707–1783), the historian and mathematician Christian Goldbach (1690–1764) expressed the belief that every integer greater than 5 is the sum of three primes. (See the letter at http://www.euler2007.com/Letter_1742-Mathematics.htm Euler replied, pointing out that Goldbach's statement is equivalent to the conjecture that every even integer greater than or equal to 4 is the sum of two primes. He went on to note, "that every even number is a sum of two primes, I consider an entirely certain theorem in spite of that I am not able to demonstrate it." Progress in proving the Goldbach conjecture has been slow. In the best effort to date, Chen Jing-Run proved in 1966 that beyond some large number, every even integer may be written as the sum of a prime number and a number that is either a prime or a product of two primes.

92. La Conjecture De GOLDBACH http://serge.bertorello.free.fr/math/goldbach.html

La conjecture de GOLDBACH "Croire tout découvert est une erreur profonde : C'est prendre l'horizon pour les bornes du monde" Camille FLAMMARION (1842 - 1925) Une conjecture est une affirmation qui n'a pas encore été prouvée. Si une conjecture est démontrée, elle devient un théorème. Une des conjectures les plus célèbres est celle que Christian GOLDBACH (1690-1764) a exprimée en 1742 en s'adressant à son collègue mathématicien Leonhard EULER (1707-1783). Christian GOLDBACH a affirmé : «Tout nombre pair, strictement supérieur à deux, est la somme de deux nombres premiers.» Pour bien comprendre cette proposition, considérons les définitions suivantes : - Un nombre pair est un multiple de 2. Autrement dit, un nombre pair est un nombre différent de zéro qui se termine par le chiffre 0, 2, 4, 6 ou 8. - Un nombre premier est un nombre qui ne peut être divisé que par 1 ou par lui-même. Voyez éventuellement la définition des nombres premiers dans l'article sur les nombres curieux. Considérons quelques exemples : Ces exemples vérifient bien la conjecture de GOLDBACH. Essayez vous-même d'en trouver d'autres.
