Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607814, here are decompositions:

23 + 31607791 = 31607814
31 + 31607783 = 31607814
67 + 31607747 = 31607814
97 + 31607717 = 31607814
127 + 31607687 = 31607814
131 + 31607683 = 31607814
233 + 31607581 = 31607814
263 + 31607551 = 31607814

Showing the first eight; more decompositions exist.
