Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660816, here are decompositions:

19 + 8660797 = 8660816
127 + 8660689 = 8660816
163 + 8660653 = 8660816
193 + 8660623 = 8660816
277 + 8660539 = 8660816
313 + 8660503 = 8660816
349 + 8660467 = 8660816
379 + 8660437 = 8660816

Showing the first eight; more decompositions exist.
