Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612704, here are decompositions:

37 + 31612667 = 31612704
41 + 31612663 = 31612704
43 + 31612661 = 31612704
83 + 31612621 = 31612704
107 + 31612597 = 31612704
131 + 31612573 = 31612704
157 + 31612547 = 31612704
173 + 31612531 = 31612704

Showing the first eight; more decompositions exist.
