Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623512, here are decompositions:

83 + 8623429 = 8623512
89 + 8623423 = 8623512
103 + 8623409 = 8623512
173 + 8623339 = 8623512
193 + 8623319 = 8623512
251 + 8623261 = 8623512
263 + 8623249 = 8623512
389 + 8623123 = 8623512

Showing the first eight; more decompositions exist.
