Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166226, here are decompositions:

7 + 166219 = 166226
19 + 166207 = 166226
37 + 166189 = 166226
43 + 166183 = 166226
79 + 166147 = 166226
127 + 166099 = 166226
163 + 166063 = 166226
199 + 166027 = 166226

Showing the first eight; more decompositions exist.
