Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166810, here are decompositions:

3 + 166807 = 166810
11 + 166799 = 166810
29 + 166781 = 166810
71 + 166739 = 166810
107 + 166703 = 166810
131 + 166679 = 166810
167 + 166643 = 166810
179 + 166631 = 166810

Showing the first eight; more decompositions exist.
