Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623566, here are decompositions:

19 + 8623547 = 8623566
37 + 8623529 = 8623566
43 + 8623523 = 8623566
47 + 8623519 = 8623566
137 + 8623429 = 8623566
157 + 8623409 = 8623566
173 + 8623393 = 8623566
227 + 8623339 = 8623566

Showing the first eight; more decompositions exist.
