Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550062, here are decompositions:

41 + 31550021 = 31550062
83 + 31549979 = 31550062
233 + 31549829 = 31550062
263 + 31549799 = 31550062
281 + 31549781 = 31550062
311 + 31549751 = 31550062
563 + 31549499 = 31550062
659 + 31549403 = 31550062

Showing the first eight; more decompositions exist.
