Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517498, here are decompositions:

7 + 31517491 = 31517498
31 + 31517467 = 31517498
109 + 31517389 = 31517498
349 + 31517149 = 31517498
487 + 31517011 = 31517498
547 + 31516951 = 31517498
619 + 31516879 = 31517498
709 + 31516789 = 31517498

Showing the first eight; more decompositions exist.
