Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623718, here are decompositions:

31 + 8623687 = 8623718
67 + 8623651 = 8623718
79 + 8623639 = 8623718
97 + 8623621 = 8623718
139 + 8623579 = 8623718
199 + 8623519 = 8623718
379 + 8623339 = 8623718
457 + 8623261 = 8623718

Showing the first eight; more decompositions exist.
