Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607956, here are decompositions:

47 + 31607909 = 31607956
53 + 31607903 = 31607956
59 + 31607897 = 31607956
89 + 31607867 = 31607956
167 + 31607789 = 31607956
173 + 31607783 = 31607956
239 + 31607717 = 31607956
269 + 31607687 = 31607956

Showing the first eight; more decompositions exist.
