Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166018, here are decompositions:

5 + 166013 = 166018
71 + 165947 = 166018
131 + 165887 = 166018
239 + 165779 = 166018
269 + 165749 = 166018
311 + 165707 = 166018
317 + 165701 = 166018
401 + 165617 = 166018

Showing the first eight; more decompositions exist.
