Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539064, here are decompositions:

3 + 31539061 = 31539064
17 + 31539047 = 31539064
113 + 31538951 = 31539064
257 + 31538807 = 31539064
311 + 31538753 = 31539064
353 + 31538711 = 31539064
503 + 31538561 = 31539064
587 + 31538477 = 31539064

Showing the first eight; more decompositions exist.
