Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166238, here are decompositions:

19 + 166219 = 166238
31 + 166207 = 166238
139 + 166099 = 166238
157 + 166081 = 166238
211 + 166027 = 166238
277 + 165961 = 166238
307 + 165931 = 166238
337 + 165901 = 166238

Showing the first eight; more decompositions exist.
