Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607850, here are decompositions:

11 + 31607839 = 31607850
19 + 31607831 = 31607850
59 + 31607791 = 31607850
61 + 31607789 = 31607850
67 + 31607783 = 31607850
103 + 31607747 = 31607850
163 + 31607687 = 31607850
167 + 31607683 = 31607850

Showing the first eight; more decompositions exist.
