楼主先生好！偶数14000000020地素数对真值您能求出吗？（只要总数）求帮助，谢谢！

这个才11位数，能求出来总数，但程序慢，得几个小时，上班呢，在单位电脑上试试吧，还要不影响工作，消耗时间更长。

谢谢！是14000000010这个数，不是14000000020；不急，有时间再帮忙。

14000000010=2*3*5*79*293*20161该偶数能被3整除且素因子个数多，总素数和对会很多。
14000000020=2*2*5*700000001而该偶数不能被3整除且不相同的素因子个数没有超过3个，所以，素数和对较少。
√14000000010=118321,先算一下118321内的素数能产生几对该偶数的素数和对：

1709*1709=2920681，所以，总数不会超过2920681，这是个简单的估测，不准确，仅仅做个参考。

重生888@

谢谢！可能不准。首先是少一位数，如果是29206810，再乘以2=58413620差不多。感谢帮忙！

这个是估计值，是上限还是下限也不确定的，仅仅做个参考而已。还可以这样估计：
14000000010/2=7000000005，
7000000005/118321=59161，
59161*1709=101106149.

这个大了，比你算的还多1位。当然，仅仅做个参考，不是确定值，程序结果还没有出来，程序结果是实际值，程序速度慢，电脑还要进行其他工作，可能影响程序速度了。
