"""357. Prime generating integers
https://projecteuler.net/problem=357

Consider the divisors of 30: 1,2,3,5,6,10,15,30.  
It can be seen that for every divisor d of 30, d+30/d is prime.

Find the sum of all positive integers n not exceeding 100 000 000  
such that for every divisor d of n, d+n/d is prime.
