Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639676, here are decompositions:

13 + 8639663 = 8639676
29 + 8639647 = 8639676
37 + 8639639 = 8639676
79 + 8639597 = 8639676
109 + 8639567 = 8639676
113 + 8639563 = 8639676
127 + 8639549 = 8639676
137 + 8639539 = 8639676

Showing the first eight; more decompositions exist.
