Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166006, here are decompositions:

23 + 165983 = 166006
59 + 165947 = 166006
149 + 165857 = 166006
173 + 165833 = 166006
227 + 165779 = 166006
257 + 165749 = 166006
293 + 165713 = 166006
353 + 165653 = 166006

Showing the first eight; more decompositions exist.
