Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626680, here are decompositions:

11 + 8626669 = 8626680
37 + 8626643 = 8626680
59 + 8626621 = 8626680
67 + 8626613 = 8626680
103 + 8626577 = 8626680
131 + 8626549 = 8626680
151 + 8626529 = 8626680
163 + 8626517 = 8626680

Showing the first eight; more decompositions exist.
