Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623656, here are decompositions:

5 + 8623651 = 8623656
17 + 8623639 = 8623656
37 + 8623619 = 8623656
53 + 8623603 = 8623656
73 + 8623583 = 8623656
109 + 8623547 = 8623656
127 + 8623529 = 8623656
137 + 8623519 = 8623656

Showing the first eight; more decompositions exist.
