Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549162, here are decompositions:

179 + 31548983 = 31549162
419 + 31548743 = 31549162
503 + 31548659 = 31549162
509 + 31548653 = 31549162
521 + 31548641 = 31549162
569 + 31548593 = 31549162
599 + 31548563 = 31549162
641 + 31548521 = 31549162

Showing the first eight; more decompositions exist.
