Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517204, here are decompositions:

7 + 31517197 = 31517204
193 + 31517011 = 31517204
211 + 31516993 = 31517204
223 + 31516981 = 31517204
571 + 31516633 = 31517204
577 + 31516627 = 31517204
601 + 31516603 = 31517204
661 + 31516543 = 31517204

Showing the first eight; more decompositions exist.
