Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166214, here are decompositions:

7 + 166207 = 166214
31 + 166183 = 166214
67 + 166147 = 166214
151 + 166063 = 166214
193 + 166021 = 166214
283 + 165931 = 166214
313 + 165901 = 166214
331 + 165883 = 166214

Showing the first eight; more decompositions exist.
