Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166206, here are decompositions:

17 + 166189 = 166206
23 + 166183 = 166206
37 + 166169 = 166206
59 + 166147 = 166206
107 + 166099 = 166206
163 + 166043 = 166206
179 + 166027 = 166206
193 + 166013 = 166206

Showing the first eight; more decompositions exist.
