Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166582, here are decompositions:

11 + 166571 = 166582
41 + 166541 = 166582
173 + 166409 = 166582
179 + 166403 = 166582
233 + 166349 = 166582
263 + 166319 = 166582
281 + 166301 = 166582
293 + 166289 = 166582

Showing the first eight; more decompositions exist.
