Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550894, here are decompositions:

43 + 31550851 = 31550894
61 + 31550833 = 31550894
97 + 31550797 = 31550894
103 + 31550791 = 31550894
163 + 31550731 = 31550894
223 + 31550671 = 31550894
283 + 31550611 = 31550894
307 + 31550587 = 31550894

Showing the first eight; more decompositions exist.
