Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550822, here are decompositions:

19 + 31550803 = 31550822
31 + 31550791 = 31550822
151 + 31550671 = 31550822
211 + 31550611 = 31550822
223 + 31550599 = 31550822
229 + 31550593 = 31550822
241 + 31550581 = 31550822
283 + 31550539 = 31550822

Showing the first eight; more decompositions exist.
