Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166528, here are decompositions:

41 + 166487 = 166528
71 + 166457 = 166528
179 + 166349 = 166528
227 + 166301 = 166528
239 + 166289 = 166528
269 + 166259 = 166528
281 + 166247 = 166528
359 + 166169 = 166528

Showing the first eight; more decompositions exist.
