Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623568, here are decompositions:

139 + 8623429 = 8623568
211 + 8623357 = 8623568
229 + 8623339 = 8623568
277 + 8623291 = 8623568
307 + 8623261 = 8623568
487 + 8623081 = 8623568
691 + 8622877 = 8623568
727 + 8622841 = 8623568

Showing the first eight; more decompositions exist.
