Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623678, here are decompositions:

17 + 8623661 = 8623678
59 + 8623619 = 8623678
131 + 8623547 = 8623678
149 + 8623529 = 8623678
269 + 8623409 = 8623678
359 + 8623319 = 8623678
431 + 8623247 = 8623678
617 + 8623061 = 8623678

Showing the first eight; more decompositions exist.
