Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550032, here are decompositions:

5 + 31550027 = 31550032
11 + 31550021 = 31550032
53 + 31549979 = 31550032
113 + 31549919 = 31550032
233 + 31549799 = 31550032
251 + 31549781 = 31550032
281 + 31549751 = 31550032
383 + 31549649 = 31550032

Showing the first eight; more decompositions exist.
