Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626650, here are decompositions:

7 + 8626643 = 8626650
29 + 8626621 = 8626650
37 + 8626613 = 8626650
47 + 8626603 = 8626650
73 + 8626577 = 8626650
101 + 8626549 = 8626650
157 + 8626493 = 8626650
163 + 8626487 = 8626650

Showing the first eight; more decompositions exist.
