Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470064, here are decompositions:

251 + 31469813 = 31470064
281 + 31469783 = 31470064
443 + 31469621 = 31470064
503 + 31469561 = 31470064
617 + 31469447 = 31470064
641 + 31469423 = 31470064
653 + 31469411 = 31470064
677 + 31469387 = 31470064

Showing the first eight; more decompositions exist.
