Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661306, here are decompositions:

53 + 8661253 = 8661306
67 + 8661239 = 8661306
83 + 8661223 = 8661306
89 + 8661217 = 8661306
103 + 8661203 = 8661306
109 + 8661197 = 8661306
113 + 8661193 = 8661306
257 + 8661049 = 8661306

Showing the first eight; more decompositions exist.
