Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661264, here are decompositions:

11 + 8661253 = 8661264
13 + 8661251 = 8661264
23 + 8661241 = 8661264
41 + 8661223 = 8661264
47 + 8661217 = 8661264
61 + 8661203 = 8661264
67 + 8661197 = 8661264
71 + 8661193 = 8661264

Showing the first eight; more decompositions exist.
