Goldbach's conjecture proof By Wadï Mami
Abstract
Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states that every even natural number greater than 2 is the sum of two prime numbers. ---------------------------------------------------------------------------------------------- A prime number must be an odd number The sum of 2 odd numbers is an even number Then The sum of two prime numbers is an even number (A). Erdös Theorem : For every integer n > 1, it exists always a prime number between n and 2n (Source : Le Beau livre des Maths De Pythagore à la 57 dimension DUNOD edition, author Clifford A.Pickover) By récurrence of Erdös Theorem mentioned above and (A) There is always k even number which is the sum of two prime numbers p and q. (B) p for n n <= p < =2n (i) q for n/2 n / 2<= q <= n (j) (i) + (j) n + n /2 <= p+q <= 3n ie 3n/2 <= p+q <= 3n wich implies k= p+q is an even number because of (A) and n integer > 1 and k is between lower limit n+ n/2 and upper limit 3n We can state then every even natural number greater than 2 is the sum of 2 prime numbers (what needed to be demonstrated) Goldbach’s conjecture proven.
