A new conjecture about primes
_____________________________

Any number ending by 1,3,7 or 9 leads to an infinity of primes ending by that number.

For instance, the number 9999 leads to the primes 49999, 59999, 79999, 139999, 179999, 199999, 239999, 289999, 329999, 379999, 389999, 409999, 419999, 529999, etc.


This is contained within Dirichlet's theorem on arithmetic
progressions:
