Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607150, here are decompositions:

13 + 31607137 = 31607150
103 + 31607047 = 31607150
193 + 31606957 = 31607150
199 + 31606951 = 31607150
271 + 31606879 = 31607150
397 + 31606753 = 31607150
409 + 31606741 = 31607150
439 + 31606711 = 31607150

Showing the first eight; more decompositions exist.
