Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620012, here are decompositions:

239 + 8619773 = 8620012
293 + 8619719 = 8620012
389 + 8619623 = 8620012
419 + 8619593 = 8620012
461 + 8619551 = 8620012
503 + 8619509 = 8620012
521 + 8619491 = 8620012
659 + 8619353 = 8620012

Showing the first eight; more decompositions exist.
