Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166330, here are decompositions:

11 + 166319 = 166330
29 + 166301 = 166330
41 + 166289 = 166330
71 + 166259 = 166330
83 + 166247 = 166330
173 + 166157 = 166330
179 + 166151 = 166330
317 + 166013 = 166330

Showing the first eight; more decompositions exist.
