Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550612, here are decompositions:

13 + 31550599 = 31550612
19 + 31550593 = 31550612
31 + 31550581 = 31550612
43 + 31550569 = 31550612
73 + 31550539 = 31550612
103 + 31550509 = 31550612
151 + 31550461 = 31550612
211 + 31550401 = 31550612

Showing the first eight; more decompositions exist.
