Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549504, here are decompositions:

5 + 31549499 = 31549504
53 + 31549451 = 31549504
101 + 31549403 = 31549504
113 + 31549391 = 31549504
131 + 31549373 = 31549504
167 + 31549337 = 31549504
227 + 31549277 = 31549504
263 + 31549241 = 31549504

Showing the first eight; more decompositions exist.
