Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549246, here are decompositions:

5 + 31549241 = 31549246
227 + 31549019 = 31549246
263 + 31548983 = 31549246
293 + 31548953 = 31549246
389 + 31548857 = 31549246
479 + 31548767 = 31549246
503 + 31548743 = 31549246
569 + 31548677 = 31549246

Showing the first eight; more decompositions exist.
