Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549528, here are decompositions:

29 + 31549499 = 31549528
89 + 31549439 = 31549528
137 + 31549391 = 31549528
191 + 31549337 = 31549528
251 + 31549277 = 31549528
347 + 31549181 = 31549528
509 + 31549019 = 31549528
761 + 31548767 = 31549528

Showing the first eight; more decompositions exist.
