Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623666, here are decompositions:

5 + 8623661 = 8623666
47 + 8623619 = 8623666
83 + 8623583 = 8623666
137 + 8623529 = 8623666
257 + 8623409 = 8623666
347 + 8623319 = 8623666
419 + 8623247 = 8623666
563 + 8623103 = 8623666

Showing the first eight; more decompositions exist.
