Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661310, here are decompositions:

29 + 8661281 = 8661310
59 + 8661251 = 8661310
71 + 8661239 = 8661310
107 + 8661203 = 8661310
113 + 8661197 = 8661310
137 + 8661173 = 8661310
149 + 8661161 = 8661310
173 + 8661137 = 8661310

Showing the first eight; more decompositions exist.
