Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517026, here are decompositions:

5 + 31517021 = 31517026
53 + 31516973 = 31517026
137 + 31516889 = 31517026
239 + 31516787 = 31517026
269 + 31516757 = 31517026
467 + 31516559 = 31517026
503 + 31516523 = 31517026
557 + 31516469 = 31517026

Showing the first eight; more decompositions exist.
