Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607892, here are decompositions:

23 + 31607869 = 31607892
53 + 31607839 = 31607892
61 + 31607831 = 31607892
101 + 31607791 = 31607892
103 + 31607789 = 31607892
109 + 31607783 = 31607892
263 + 31607629 = 31607892
293 + 31607599 = 31607892

Showing the first eight; more decompositions exist.
