Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517962, here are decompositions:

11 + 31517951 = 31517962
53 + 31517909 = 31517962
83 + 31517879 = 31517962
101 + 31517861 = 31517962
233 + 31517729 = 31517962
239 + 31517723 = 31517962
263 + 31517699 = 31517962
383 + 31517579 = 31517962

Showing the first eight; more decompositions exist.
