Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624128, here are decompositions:

17 + 8624111 = 8624128
101 + 8624027 = 8624128
167 + 8623961 = 8624128
281 + 8623847 = 8624128
449 + 8623679 = 8624128
467 + 8623661 = 8624128
509 + 8623619 = 8624128
599 + 8623529 = 8624128

Showing the first eight; more decompositions exist.
