Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549324, here are decompositions:

47 + 31549277 = 31549324
83 + 31549241 = 31549324
281 + 31549043 = 31549324
467 + 31548857 = 31549324
557 + 31548767 = 31549324
647 + 31548677 = 31549324
683 + 31548641 = 31549324
761 + 31548563 = 31549324

Showing the first eight; more decompositions exist.
