哥德巴赫猜想:

将一给定的偶数表示成两个质数之和被称之为此数的哥德巴赫分割。例如，



4 = 2 + 2

6 = 3 + 3

8 = 3 + 5

10 = 3 + 7 = 5 + 5

12 = 5 + 7

14 = 3 + 11 = 7 + 7

…

换句话说，哥德巴赫猜想主张每个大于等于 4 的偶数都是哥德巴赫数－可表示成两个质数之和的数。[1]另有对奇数的相似猜想，称之为李维猜想。

-Goldbach s conjecture:

Will give one set even express into a number of both qualitative and has been described as the number of Goldbach partitions. For example,

　 4 = 2+ 2

　 6 = 3+ 3

　 8 = 3+ 5

10 = 3+ 7 = 5+ 5

12 = 5+ 7

14 = 3+ 11 = 7+ 7

...

In other words, the Goldbach conjecture that every even number greater than or equal to 4 are Goldbach few- can be expressed as the number of both qualitative and few. [1] Another odd similarity to the suspect, known as Li guess.
