Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510586, here are decompositions:

13 + 31510573 = 31510586
97 + 31510489 = 31510586
127 + 31510459 = 31510586
139 + 31510447 = 31510586
199 + 31510387 = 31510586
223 + 31510363 = 31510586
277 + 31510309 = 31510586
577 + 31510009 = 31510586

Showing the first eight; more decompositions exist.
