Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517564, here are decompositions:

7 + 31517557 = 31517564
31 + 31517533 = 31517564
37 + 31517527 = 31517564
73 + 31517491 = 31517564
97 + 31517467 = 31517564
151 + 31517413 = 31517564
157 + 31517407 = 31517564
367 + 31517197 = 31517564

Showing the first eight; more decompositions exist.
