Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626656, here are decompositions:

13 + 8626643 = 8626656
43 + 8626613 = 8626656
53 + 8626603 = 8626656
79 + 8626577 = 8626656
107 + 8626549 = 8626656
127 + 8626529 = 8626656
139 + 8626517 = 8626656
149 + 8626507 = 8626656

Showing the first eight; more decompositions exist.
