Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629018, here are decompositions:

227 + 8628791 = 8629018
239 + 8628779 = 8629018
389 + 8628629 = 8629018
467 + 8628551 = 8629018
569 + 8628449 = 8629018
641 + 8628377 = 8629018
659 + 8628359 = 8629018
857 + 8628161 = 8629018

Showing the first eight; more decompositions exist.
