Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706816, here are decompositions:

23 + 8706793 = 8706816
73 + 8706743 = 8706816
89 + 8706727 = 8706816
109 + 8706707 = 8706816
149 + 8706667 = 8706816
229 + 8706587 = 8706816
263 + 8706553 = 8706816
269 + 8706547 = 8706816

Showing the first eight; more decompositions exist.
