Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661718, here are decompositions:

11 + 8661707 = 8661718
29 + 8661689 = 8661718
89 + 8661629 = 8661718
137 + 8661581 = 8661718
227 + 8661491 = 8661718
239 + 8661479 = 8661718
257 + 8661461 = 8661718
281 + 8661437 = 8661718

Showing the first eight; more decompositions exist.
