Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608944, here are decompositions:

7 + 31608937 = 31608944
61 + 31608883 = 31608944
127 + 31608817 = 31608944
151 + 31608793 = 31608944
223 + 31608721 = 31608944
277 + 31608667 = 31608944
463 + 31608481 = 31608944
607 + 31608337 = 31608944

Showing the first eight; more decompositions exist.
