Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724922, here are decompositions:

281 + 8724641 = 8724922
443 + 8724479 = 8724922
461 + 8724461 = 8724922
593 + 8724329 = 8724922
599 + 8724323 = 8724922
653 + 8724269 = 8724922
659 + 8724263 = 8724922
761 + 8724161 = 8724922

Showing the first eight; more decompositions exist.
