Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511606, here are decompositions:

37 + 31511569 = 31511606
67 + 31511539 = 31511606
73 + 31511533 = 31511606
79 + 31511527 = 31511606
103 + 31511503 = 31511606
229 + 31511377 = 31511606
439 + 31511167 = 31511606
463 + 31511143 = 31511606

Showing the first eight; more decompositions exist.
