Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18166, here are decompositions:

17 + 18149 = 18166
23 + 18143 = 18166
47 + 18119 = 18166
89 + 18077 = 18166
107 + 18059 = 18166
179 + 17987 = 18166
227 + 17939 = 18166
257 + 17909 = 18166

Showing the first eight; more decompositions exist.
