Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517762, here are decompositions:

13 + 31517749 = 31517762
61 + 31517701 = 31517762
109 + 31517653 = 31517762
229 + 31517533 = 31517762
271 + 31517491 = 31517762
349 + 31517413 = 31517762
373 + 31517389 = 31517762
613 + 31517149 = 31517762

Showing the first eight; more decompositions exist.
