Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639026, here are decompositions:

29 + 8638997 = 8639026
59 + 8638967 = 8639026
89 + 8638937 = 8639026
173 + 8638853 = 8639026
293 + 8638733 = 8639026
443 + 8638583 = 8639026
509 + 8638517 = 8639026
563 + 8638463 = 8639026

Showing the first eight; more decompositions exist.
