Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3166, here are decompositions:

3 + 3163 = 3166
29 + 3137 = 3166
47 + 3119 = 3166
83 + 3083 = 3166
167 + 2999 = 3166
197 + 2969 = 3166
227 + 2939 = 3166
239 + 2927 = 3166

Showing the first eight; more decompositions exist.
