Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716666, here are decompositions:

3 + 8716663 = 8716666
5 + 8716661 = 8716666
47 + 8716619 = 8716666
53 + 8716613 = 8716666
83 + 8716583 = 8716666
113 + 8716553 = 8716666
197 + 8716469 = 8716666
227 + 8716439 = 8716666

Showing the first eight; more decompositions exist.
