Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517594, here are decompositions:

7 + 31517587 = 31517594
37 + 31517557 = 31517594
61 + 31517533 = 31517594
67 + 31517527 = 31517594
103 + 31517491 = 31517594
127 + 31517467 = 31517594
181 + 31517413 = 31517594
397 + 31517197 = 31517594

Showing the first eight; more decompositions exist.
