Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166966, here are decompositions:

17 + 166949 = 166966
47 + 166919 = 166966
113 + 166853 = 166966
167 + 166799 = 166966
227 + 166739 = 166966
263 + 166703 = 166966
347 + 166619 = 166966
353 + 166613 = 166966

Showing the first eight; more decompositions exist.
