Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601166, here are decompositions:

3 + 8601163 = 8601166
23 + 8601143 = 8601166
53 + 8601113 = 8601166
59 + 8601107 = 8601166
83 + 8601083 = 8601166
89 + 8601077 = 8601166
137 + 8601029 = 8601166
269 + 8600897 = 8601166

Showing the first eight; more decompositions exist.
