Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539134, here are decompositions:

61 + 31539073 = 31539134
73 + 31539061 = 31539134
127 + 31539007 = 31539134
307 + 31538827 = 31539134
421 + 31538713 = 31539134
463 + 31538671 = 31539134
577 + 31538557 = 31539134
607 + 31538527 = 31539134

Showing the first eight; more decompositions exist.
