Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166012, here are decompositions:

29 + 165983 = 166012
71 + 165941 = 166012
179 + 165833 = 166012
233 + 165779 = 166012
263 + 165749 = 166012
293 + 165719 = 166012
311 + 165701 = 166012
359 + 165653 = 166012

Showing the first eight; more decompositions exist.
