Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13166, here are decompositions:

3 + 13163 = 13166
7 + 13159 = 13166
19 + 13147 = 13166
67 + 13099 = 13166
73 + 13093 = 13166
103 + 13063 = 13166
157 + 13009 = 13166
163 + 13003 = 13166

Showing the first eight; more decompositions exist.
