Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661286, here are decompositions:

5 + 8661281 = 8661286
47 + 8661239 = 8661286
83 + 8661203 = 8661286
89 + 8661197 = 8661286
113 + 8661173 = 8661286
149 + 8661137 = 8661286
167 + 8661119 = 8661286
197 + 8661089 = 8661286

Showing the first eight; more decompositions exist.
