Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623668, here are decompositions:

7 + 8623661 = 8623668
17 + 8623651 = 8623668
29 + 8623639 = 8623668
47 + 8623621 = 8623668
89 + 8623579 = 8623668
139 + 8623529 = 8623668
149 + 8623519 = 8623668
239 + 8623429 = 8623668

Showing the first eight; more decompositions exist.
