Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716986, here are decompositions:

29 + 8716957 = 8716986
43 + 8716943 = 8716986
67 + 8716919 = 8716986
97 + 8716889 = 8716986
167 + 8716819 = 8716986
227 + 8716759 = 8716986
233 + 8716753 = 8716986
277 + 8716709 = 8716986

Showing the first eight; more decompositions exist.
