Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166154, here are decompositions:

3 + 166151 = 166154
7 + 166147 = 166154
73 + 166081 = 166154
127 + 166027 = 166154
193 + 165961 = 166154
223 + 165931 = 166154
271 + 165883 = 166154
277 + 165877 = 166154

Showing the first eight; more decompositions exist.
