Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549108, here are decompositions:

89 + 31549019 = 31549108
251 + 31548857 = 31549108
359 + 31548749 = 31549108
431 + 31548677 = 31549108
449 + 31548659 = 31549108
467 + 31548641 = 31549108
557 + 31548551 = 31549108
587 + 31548521 = 31549108

Showing the first eight; more decompositions exist.
