Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550664, here are decompositions:

37 + 31550627 = 31550664
53 + 31550611 = 31550664
71 + 31550593 = 31550664
83 + 31550581 = 31550664
107 + 31550557 = 31550664
127 + 31550537 = 31550664
193 + 31550471 = 31550664
227 + 31550437 = 31550664

Showing the first eight; more decompositions exist.
