Question 289155
Find a counterexample to:The cube of a number added to the sum of five times the number and 2 is a prime number?

n is an integer number from 0 on to infinity
n^3 + (5n + 2) is a prime number ?
n	n^3 + (5n + 2)
0	2
1	8
2	20
3	44
4	86
5	152
none of these results, well except when n=0 looks prime to me
