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…
