Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666648, here are decompositions:

157 + 8666491 = 8666648
229 + 8666419 = 8666648
379 + 8666269 = 8666648
631 + 8666017 = 8666648
709 + 8665939 = 8666648
751 + 8665897 = 8666648
997 + 8665651 = 8666648
1087 + 8665561 = 8666648

Showing the first eight; more decompositions exist.
