Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623470, here are decompositions:

41 + 8623429 = 8623470
47 + 8623423 = 8623470
61 + 8623409 = 8623470
113 + 8623357 = 8623470
131 + 8623339 = 8623470
151 + 8623319 = 8623470
179 + 8623291 = 8623470
223 + 8623247 = 8623470

Showing the first eight; more decompositions exist.
