Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607384, here are decompositions:

43 + 31607341 = 31607384
103 + 31607281 = 31607384
157 + 31607227 = 31607384
283 + 31607101 = 31607384
337 + 31607047 = 31607384
421 + 31606963 = 31607384
433 + 31606951 = 31607384
631 + 31606753 = 31607384

Showing the first eight; more decompositions exist.
