Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549228, here are decompositions:

47 + 31549181 = 31549228
461 + 31548767 = 31549228
479 + 31548749 = 31549228
569 + 31548659 = 31549228
587 + 31548641 = 31549228
677 + 31548551 = 31549228
701 + 31548527 = 31549228
761 + 31548467 = 31549228

Showing the first eight; more decompositions exist.
