Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607186, here are decompositions:

139 + 31607047 = 31607186
223 + 31606963 = 31607186
229 + 31606957 = 31607186
283 + 31606903 = 31607186
307 + 31606879 = 31607186
433 + 31606753 = 31607186
607 + 31606579 = 31607186
643 + 31606543 = 31607186

Showing the first eight; more decompositions exist.
