Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623518, here are decompositions:

89 + 8623429 = 8623518
109 + 8623409 = 8623518
179 + 8623339 = 8623518
199 + 8623319 = 8623518
227 + 8623291 = 8623518
257 + 8623261 = 8623518
269 + 8623249 = 8623518
271 + 8623247 = 8623518

Showing the first eight; more decompositions exist.
