大偶数可表示为两个奇素数之和

A big even number as the sum of two odd prime numbers

引进了“当P =2a +1 ,a∈N ,且a≠ 2uv +u +v , u、v∈N ,则P =2a +1为素数”这一与素数定义完全等价的代数表达式后 ,用一种新的筛法证明了任一大偶数皆可表示为两个奇素数之和。

In this paper,the conclusion that any big even number can be expressed as the sum of two odd prime numbers has been proved by using the sieving methed according to the quite equivalent algebra expression difinition of prime number that'P is a prime number if only if P=2a-1,a∈N,when a≠2uv+u+v,u,v∈N'.
