Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607862, here are decompositions:

5 + 31607857 = 31607862
23 + 31607839 = 31607862
31 + 31607831 = 31607862
71 + 31607791 = 31607862
73 + 31607789 = 31607862
79 + 31607783 = 31607862
173 + 31607689 = 31607862
179 + 31607683 = 31607862

Showing the first eight; more decompositions exist.
