Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166882, here are decompositions:

11 + 166871 = 166882
29 + 166853 = 166882
41 + 166841 = 166882
59 + 166823 = 166882
83 + 166799 = 166882
101 + 166781 = 166882
179 + 166703 = 166882
239 + 166643 = 166882

Showing the first eight; more decompositions exist.
