Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82164, here are decompositions:

11 + 82153 = 82164
23 + 82141 = 82164
97 + 82067 = 82164
113 + 82051 = 82164
127 + 82037 = 82164
151 + 82013 = 82164
157 + 82007 = 82164
191 + 81973 = 82164

Showing the first eight; more decompositions exist.
