Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517294, here are decompositions:

97 + 31517197 = 31517294
283 + 31517011 = 31517294
313 + 31516981 = 31517294
541 + 31516753 = 31517294
661 + 31516633 = 31517294
691 + 31516603 = 31517294
727 + 31516567 = 31517294
751 + 31516543 = 31517294

Showing the first eight; more decompositions exist.
