Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715898, here are decompositions:

11 + 8715887 = 8715898
17 + 8715881 = 8715898
137 + 8715761 = 8715898
167 + 8715731 = 8715898
179 + 8715719 = 8715898
227 + 8715671 = 8715898
239 + 8715659 = 8715898
251 + 8715647 = 8715898

Showing the first eight; more decompositions exist.
