Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607118, here are decompositions:

17 + 31607101 = 31607118
31 + 31607087 = 31607118
71 + 31607047 = 31607118
79 + 31607039 = 31607118
139 + 31606979 = 31607118
167 + 31606951 = 31607118
199 + 31606919 = 31607118
239 + 31606879 = 31607118

Showing the first eight; more decompositions exist.
