Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168194, here are decompositions:

43 + 168151 = 168194
67 + 168127 = 168194
127 + 168067 = 168194
151 + 168043 = 168194
157 + 168037 = 168194
181 + 168013 = 168194
223 + 167971 = 168194
241 + 167953 = 168194

Showing the first eight; more decompositions exist.
