Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626868, here are decompositions:

7 + 8626861 = 8626868
37 + 8626831 = 8626868
67 + 8626801 = 8626868
199 + 8626669 = 8626868
409 + 8626459 = 8626868
571 + 8626297 = 8626868
619 + 8626249 = 8626868
631 + 8626237 = 8626868

Showing the first eight; more decompositions exist.
