Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550096, here are decompositions:

3 + 31550093 = 31550096
163 + 31549933 = 31550096
199 + 31549897 = 31550096
223 + 31549873 = 31550096
367 + 31549729 = 31550096
379 + 31549717 = 31550096
433 + 31549663 = 31550096
499 + 31549597 = 31550096

Showing the first eight; more decompositions exist.
