Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607086, here are decompositions:

47 + 31607039 = 31607086
89 + 31606997 = 31607086
107 + 31606979 = 31607086
113 + 31606973 = 31607086
167 + 31606919 = 31607086
239 + 31606847 = 31607086
257 + 31606829 = 31607086
359 + 31606727 = 31607086

Showing the first eight; more decompositions exist.
