Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166346, here are decompositions:

43 + 166303 = 166346
73 + 166273 = 166346
109 + 166237 = 166346
127 + 166219 = 166346
139 + 166207 = 166346
157 + 166189 = 166346
163 + 166183 = 166346
199 + 166147 = 166346

Showing the first eight; more decompositions exist.
