Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716866, here are decompositions:

5 + 8716861 = 8716866
13 + 8716853 = 8716866
23 + 8716843 = 8716866
47 + 8716819 = 8716866
83 + 8716783 = 8716866
97 + 8716769 = 8716866
107 + 8716759 = 8716866
113 + 8716753 = 8716866

Showing the first eight; more decompositions exist.
