Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517064, here are decompositions:

37 + 31517027 = 31517064
43 + 31517021 = 31517064
53 + 31517011 = 31517064
71 + 31516993 = 31517064
83 + 31516981 = 31517064
113 + 31516951 = 31517064
223 + 31516841 = 31517064
277 + 31516787 = 31517064

Showing the first eight; more decompositions exist.
