Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166512, here are decompositions:

41 + 166471 = 166512
83 + 166429 = 166512
103 + 166409 = 166512
109 + 166403 = 166512
113 + 166399 = 166512
149 + 166363 = 166512
163 + 166349 = 166512
193 + 166319 = 166512

Showing the first eight; more decompositions exist.
