Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661262, here are decompositions:

11 + 8661251 = 8661262
23 + 8661239 = 8661262
59 + 8661203 = 8661262
89 + 8661173 = 8661262
101 + 8661161 = 8661262
173 + 8661089 = 8661262
293 + 8660969 = 8661262
353 + 8660909 = 8661262

Showing the first eight; more decompositions exist.
