Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661256, here are decompositions:

3 + 8661253 = 8661256
5 + 8661251 = 8661256
17 + 8661239 = 8661256
53 + 8661203 = 8661256
59 + 8661197 = 8661256
83 + 8661173 = 8661256
137 + 8661119 = 8661256
167 + 8661089 = 8661256

Showing the first eight; more decompositions exist.
