Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517264, here are decompositions:

67 + 31517197 = 31517264
271 + 31516993 = 31517264
283 + 31516981 = 31517264
313 + 31516951 = 31517264
487 + 31516777 = 31517264
631 + 31516633 = 31517264
661 + 31516603 = 31517264
853 + 31516411 = 31517264

Showing the first eight; more decompositions exist.
