求素数，并且保存于文本文件，并且下次执行还可以接着上次的结果继续找下去
所以总有一天你会找到最大的素数……每天就像挂Q一样挂一下这个程序就行了-Seek primes, and stored in a text file, and the next performance can also be followed by the last results continue to look down so that one day you will find the largest prime number ... ... the same day, just hanging Q hang about this program on the list ... ...
