[seqfan]回复：插入“+”并始终获得素数

[拉尔斯·布隆伯格]

下面是我发现的400个S值。
在此之后，斜坡变得非常陡峭，需要一些技巧才能在合理的时间内继续前进。

阿尔瓦·米恩：[seqfan]插入“+”，总是得到一个质数
你好SeqFans，
看看这些整数：
110,112,116,118,130,136
如果你在里面插入一个“+”号，你总是会得到一个质数，无论在哪里：
110-->1+10=11和11+0=11
112-->1+12=13和11+2=13
116-->17
118 --> 19
130-->1+30=31和13+0=13
136-->1+36=37和13+6=19
101不是具有此属性的整数，因为不允许1+01=2（没有以“0”开头的子字符串）。
我猜S，共享此属性的整数序列）将这样开始：
S=11、12、14、16、20、21、23、25、29、30、32、34、38、41、43、47、49、50、52、56、58、61、65、67、70、74、76、83、85、89、92、94、98、110、112、116、118、130、136，。。。
最佳，
É.
