Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166364, here are decompositions:

7 + 166357 = 166364
13 + 166351 = 166364
61 + 166303 = 166364
67 + 166297 = 166364
127 + 166237 = 166364
157 + 166207 = 166364
181 + 166183 = 166364
283 + 166081 = 166364

Showing the first eight; more decompositions exist.
