Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539034, here are decompositions:

47 + 31538987 = 31539034
83 + 31538951 = 31539034
227 + 31538807 = 31539034
281 + 31538753 = 31539034
557 + 31538477 = 31539034
701 + 31538333 = 31539034
773 + 31538261 = 31539034
827 + 31538207 = 31539034

Showing the first eight; more decompositions exist.
