Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517756, here are decompositions:

7 + 31517749 = 31517756
103 + 31517653 = 31517756
139 + 31517617 = 31517756
199 + 31517557 = 31517756
223 + 31517533 = 31517756
229 + 31517527 = 31517756
349 + 31517407 = 31517756
367 + 31517389 = 31517756

Showing the first eight; more decompositions exist.
