Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550336, here are decompositions:

7 + 31550329 = 31550336
79 + 31550257 = 31550336
157 + 31550179 = 31550336
199 + 31550137 = 31550336
229 + 31550107 = 31550336
373 + 31549963 = 31550336
439 + 31549897 = 31550336
457 + 31549879 = 31550336

Showing the first eight; more decompositions exist.
