Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166120, here are decompositions:

89 + 166031 = 166120
107 + 166013 = 166120
137 + 165983 = 166120
173 + 165947 = 166120
179 + 165941 = 166120
233 + 165887 = 166120
263 + 165857 = 166120
401 + 165719 = 166120

Showing the first eight; more decompositions exist.
