Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82166, here are decompositions:

3 + 82163 = 82166
13 + 82153 = 82166
37 + 82129 = 82166
127 + 82039 = 82166
157 + 82009 = 82166
163 + 82003 = 82166
193 + 81973 = 82166
199 + 81967 = 82166

Showing the first eight; more decompositions exist.
