那先生最后一张图片第一行
G（2086577180）=？=4448903
D（2086577180）=5/6*（W）=4353779

真值范围：
4353779/0.99<?(4448903)<4353779/0.95

重生888@

预计：
D（2053577190）=4353779/2*4=8707558

8707558/0.99<?(8940412)<4707558/0.95

不愧是工程师！七八个系数，还说是计算公式？不评论您了。下面两个偶数，是崔坤帖子里面别人发的：
D（3 ...

按现在的方法计算结果如下：
D(39910)=433，GD(39910)=407.25，infD(39910)=177.8，上限D(39910)=1027.6
D(39912)=564，GD(39912)=560.00，infD(39912)=177.8，上限D(39912)=1027.7
上限数值是用夹挤不等式的上限分工计算出来的，下限计算式是用夹挤不等式的下限计算式推论出来的。夹挤不等式中的A都取0.7ln(N)，ln(N)在计算时都约去了，则只剩下0.7参与计算系数了。

不好意思，昨天写错了，是这两个数

39900:    999
39902:    297

D(39900)=999，GD(39900)=994.96，infD(39900)=177.8，上限D(39900)=1027.4
D(39902)=298，GD(39902)=297.91，infD(39902)=177.8，上限D(39902)=1027.4

回复：
我是把1当作素数对待的，只要出现多一个素数对问题，都不用验证N-1是否为素数，必定是多了个1+(N-1)=N这个素数对，则N-1必定是素数。

不好意思，昨天写错了，是这两个数

39900:    999

G（39900）=999
D（39900）=5/3*（39900+2.5*39900/ln39900）/(ln39900)^2          F4=2.5
                   =732
D1=732*(7-1)/(7-2)*(19-1)/(19-2)=930       真值不小于930

G(39902)=732/4*1.5=274         真值不小于274
这才叫公式计算！

重生888@

你的【732】和【(7-1)/(7-2)*(19-1)/(19-2)】根据什么得出来 的？
732是公式计算值；
39900=2*2*3*5*5*7*19             因有7和19因子！

那老师、愚公老师都是在致力于提高计算精度，吴老师则频频强调下限。
学生认为下限应该是连续偶数哥猜数的 ...

还是杨先生评论有质量！希望在这里看看我的计算，给予点评，谢谢！

重生888@

你这种有选择性的作法，如何掌握？根据拉曼纽扬的偶数分类计算法则，应该是对3、5、7、19的连乘积计算，你根据什么把3、5给丢掉了？

这就是我公式的奥妙所在！

重生888@

这个奥妙有规律可言吗？具有普遍性意义吗？

当然有啦，您随便举几个数，我算给你看！
