Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716864, here are decompositions:

3 + 8716861 = 8716864
11 + 8716853 = 8716864
47 + 8716817 = 8716864
137 + 8716727 = 8716864
173 + 8716691 = 8716864
251 + 8716613 = 8716864
281 + 8716583 = 8716864
311 + 8716553 = 8716864

Showing the first eight; more decompositions exist.
