Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465916, here are decompositions:

37 + 31465879 = 31465916
67 + 31465849 = 31465916
127 + 31465789 = 31465916
337 + 31465579 = 31465916
457 + 31465459 = 31465916
499 + 31465417 = 31465916
607 + 31465309 = 31465916
673 + 31465243 = 31465916

Showing the first eight; more decompositions exist.
