Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166254, here are decompositions:

7 + 166247 = 166254
17 + 166237 = 166254
47 + 166207 = 166254
71 + 166183 = 166254
97 + 166157 = 166254
103 + 166151 = 166254
107 + 166147 = 166254
173 + 166081 = 166254

Showing the first eight; more decompositions exist.
