Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549252, here are decompositions:

11 + 31549241 = 31549252
71 + 31549181 = 31549252
233 + 31549019 = 31549252
269 + 31548983 = 31549252
503 + 31548749 = 31549252
509 + 31548743 = 31549252
593 + 31548659 = 31549252
599 + 31548653 = 31549252

Showing the first eight; more decompositions exist.
