Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607958, here are decompositions:

37 + 31607921 = 31607958
61 + 31607897 = 31607958
89 + 31607869 = 31607958
101 + 31607857 = 31607958
127 + 31607831 = 31607958
167 + 31607791 = 31607958
211 + 31607747 = 31607958
241 + 31607717 = 31607958

Showing the first eight; more decompositions exist.
