Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549126, here are decompositions:

83 + 31549043 = 31549126
107 + 31549019 = 31549126
173 + 31548953 = 31549126
269 + 31548857 = 31549126
359 + 31548767 = 31549126
383 + 31548743 = 31549126
449 + 31548677 = 31549126
467 + 31548659 = 31549126

Showing the first eight; more decompositions exist.
