Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517116, here are decompositions:

53 + 31517063 = 31517116
89 + 31517027 = 31517116
227 + 31516889 = 31517116
359 + 31516757 = 31517116
419 + 31516697 = 31517116
503 + 31516613 = 31517116
557 + 31516559 = 31517116
593 + 31516523 = 31517116

Showing the first eight; more decompositions exist.
