Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166406, here are decompositions:

3 + 166403 = 166406
7 + 166399 = 166406
13 + 166393 = 166406
43 + 166363 = 166406
103 + 166303 = 166406
109 + 166297 = 166406
199 + 166207 = 166406
223 + 166183 = 166406

Showing the first eight; more decompositions exist.
