Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661298, here are decompositions:

17 + 8661281 = 8661298
47 + 8661251 = 8661298
59 + 8661239 = 8661298
101 + 8661197 = 8661298
137 + 8661161 = 8661298
179 + 8661119 = 8661298
251 + 8661047 = 8661298
311 + 8660987 = 8661298

Showing the first eight; more decompositions exist.
