Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82178, here are decompositions:

7 + 82171 = 82178
37 + 82141 = 82178
127 + 82051 = 82178
139 + 82039 = 82178
157 + 82021 = 82178
211 + 81967 = 82178
241 + 81937 = 82178
277 + 81901 = 82178

Showing the first eight; more decompositions exist.
