Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550646, here are decompositions:

19 + 31550627 = 31550646
47 + 31550599 = 31550646
53 + 31550593 = 31550646
59 + 31550587 = 31550646
73 + 31550573 = 31550646
89 + 31550557 = 31550646
103 + 31550543 = 31550646
107 + 31550539 = 31550646

Showing the first eight; more decompositions exist.
