Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607162, here are decompositions:

61 + 31607101 = 31607162
199 + 31606963 = 31607162
211 + 31606951 = 31607162
283 + 31606879 = 31607162
409 + 31606753 = 31607162
421 + 31606741 = 31607162
619 + 31606543 = 31607162
733 + 31606429 = 31607162

Showing the first eight; more decompositions exist.
