Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517936, here are decompositions:

283 + 31517653 = 31517936
349 + 31517587 = 31517936
379 + 31517557 = 31517936
409 + 31517527 = 31517936
523 + 31517413 = 31517936
547 + 31517389 = 31517936
739 + 31517197 = 31517936
787 + 31517149 = 31517936

Showing the first eight; more decompositions exist.
