Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166828, here are decompositions:

5 + 166823 = 166828
29 + 166799 = 166828
47 + 166781 = 166828
89 + 166739 = 166828
149 + 166679 = 166828
197 + 166631 = 166828
227 + 166601 = 166828
257 + 166571 = 166828

Showing the first eight; more decompositions exist.
