Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623664, here are decompositions:

3 + 8623661 = 8623664
13 + 8623651 = 8623664
43 + 8623621 = 8623664
61 + 8623603 = 8623664
241 + 8623423 = 8623664
271 + 8623393 = 8623664
307 + 8623357 = 8623664
373 + 8623291 = 8623664

Showing the first eight; more decompositions exist.
