Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539514, here are decompositions:

47 + 31539467 = 31539514
101 + 31539413 = 31539514
113 + 31539401 = 31539514
137 + 31539377 = 31539514
431 + 31539083 = 31539514
467 + 31539047 = 31539514
563 + 31538951 = 31539514
761 + 31538753 = 31539514

Showing the first eight; more decompositions exist.
