Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607982, here are decompositions:

11 + 31607971 = 31607982
13 + 31607969 = 31607982
61 + 31607921 = 31607982
73 + 31607909 = 31607982
79 + 31607903 = 31607982
113 + 31607869 = 31607982
151 + 31607831 = 31607982
191 + 31607791 = 31607982

Showing the first eight; more decompositions exist.
