n!的双计素数对
第4列数字为双计素数对的常用对数值，已考虑了波动系数的影响，采用哈李对数计算式，当n相当大时，计算值应该接近于真实值。

n lg(n!) ln(n!) lg(1.32)+lgN-2*lg(lnN)+lg波 R2(n!)/R2((n-1)!) 波动系数

不一定，因为余项问题肯定不会接近于真实值。

没有理论证明哈李公式r2(N)=主项（1+a)中的余项a≠-1

推荐的偶数n的哥德巴赫分区（素数对）计算式是：
N2(n)=2c*n/[ln(n)*ln(n-2)]*∏(p-1)/(p-2)，p为能够整除偶数n的奇素因子，没有表明是全部素因子还是根内素因子；
与通常所说的哈李计算式相比，分母的自然对数号中的一个偶数n减了一个2，小了一点点，当n很大时，减2不会对总计算值有很大影响。
式中c——孪生素数常数，等于0.66016181584686957392…
通常计算式不减2，仅取偶数n的平方根内的奇素因子；分母减2，分数值大了一点点；波动系数取偶数n的全部奇素因子，又大了一点点；
两个大了一点点，能不能弥补通常的计算式小于偶数素数对的问题？

网页推荐的另一计算式是积分式：
N2(n)=2c*∫1/[ln(x)*ln(x-2)]*dx*∏(p-1)/(p-2)，积分区间为2至n-2，
网页没有给出积分式，这个对数积分很难计算。

推荐的偶数n的哥德 ...

偶数n的哥德巴赫分区（素数对）计算式是：
N2(n)=2c∏(p-1)/(p-2)*n/[ln(n)*ln(n-2)]中的ln(n-2)改为ln(n)基本上不影响计算结果。
所以偶数n的哥德巴赫分区（素数对）计算式是：
N2(n)=2c∏(p-1)/(p-2)*n/[ln(n)*ln(n)]，p为能够整除根号n的奇素因子，因为在实际中大于根号n的奇素因子不会增加素数对的个数，同时大于根号n的奇素因子最多只有一个即使算上也增加不了多少。所以由此可见由ln(n-2)改为ln(n)，并取偶数n以内的奇素因子不能弥补通常的计算式小于偶数素数对的问题。
同时计算式N2(n)=2c∏(p-1)/(p-2)*n/[ln(n)*ln(n)]
和我的公式r(n)～∏[(p-1)/(p-2)](n/2)∏(1-2/p)[1/2e^(-γ)]^2]等价
我们从实际上知道∏[(p-1)/(p-2)](n/2)∏(1-2/p)计算偶数里的素数对在数值比较小时精确度比较高，随着数值加大计算偶数里的素数对比实际值也在增加，根据我的公式计算偶数里的素数对比实际值最大不会超过[2e^(-γ)]^2=1.2609......倍，由此可见由ln(n-2)改为ln(n)，并取偶数n以内的奇素因子并不能弥补通常的计算式小于偶数素数对的问题。

杨计算ln(10000!)等于82108.92784，崔计算ln(10000!)等于82109;
杨计算ln(30000!)等于279274.6532，崔计算ln(30000!)等于279274.3429;
计算误差所致，没有争论必要。
