Goldbach s conjecture: Goldbach(哥德巴赫)曾经提出了一个这样的猜想: 对于2000 以内的正偶数都能够分解为两个素数之和。 要求: 该题是一个猜想,我们不去证明它,而是通过编程序来验证 该猜想是否正确。 输入: 用户从键盘任意输入一个自然数。 输出: 给出满足猜想的两个自然数。

北京大学ACM比赛题目 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. 20 = 3 + 17 = 7 + 13. 42 = 5 + 37 = 11 + 31 = 13 + 29 = 19 + 23. 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.
