Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550636, here are decompositions:

37 + 31550599 = 31550636
43 + 31550593 = 31550636
67 + 31550569 = 31550636
79 + 31550557 = 31550636
97 + 31550539 = 31550636
127 + 31550509 = 31550636
157 + 31550479 = 31550636
199 + 31550437 = 31550636

Showing the first eight; more decompositions exist.
