Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166768, here are decompositions:

29 + 166739 = 166768
89 + 166679 = 166768
101 + 166667 = 166768
137 + 166631 = 166768
149 + 166619 = 166768
167 + 166601 = 166768
197 + 166571 = 166768
227 + 166541 = 166768

Showing the first eight; more decompositions exist.
