Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661276, here are decompositions:

23 + 8661253 = 8661276
37 + 8661239 = 8661276
53 + 8661223 = 8661276
59 + 8661217 = 8661276
73 + 8661203 = 8661276
79 + 8661197 = 8661276
83 + 8661193 = 8661276
103 + 8661173 = 8661276

Showing the first eight; more decompositions exist.
