Problem Description Goldbach's Conjecture: For any even number n greater than or equal to 4, there exists at least one pair of prime numbers p1 and p2 such that n = p1 + p2. This conjecture has not been proved nor refused yet. No one is sure whether…

It was proposed by Christian Goldbach that every odd composite number can be written as the sum of a prime and twice a square. 9 = 7 + 21215 = 7 + 22221 = 3 + 23225 = 7 + 23227 = 19 + 22233 = 31 + 212 It turns out that the conjecture was false. What…
POJ 2262 Goldbach's Conjecture(素数相关) http://poj.org/problem?id=2262 题意: 给你一个[6,1000000]范围内的偶数,要你将它表示成两个素数相加和的形式.假设存在多组解,请输出两个素数差值最大的解. 分析: 首先我们用素数筛选法求出100W以内的全部素数. 筛选法求素数可见: http://blog.csdn.net/u013480600/article/details/41120083 对于给定的数X,假设存在素数a+素数b…
