Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661226, here are decompositions:

3 + 8661223 = 8661226
23 + 8661203 = 8661226
29 + 8661197 = 8661226
53 + 8661173 = 8661226
89 + 8661137 = 8661226
107 + 8661119 = 8661226
137 + 8661089 = 8661226
179 + 8661047 = 8661226

Showing the first eight; more decompositions exist.
