Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166798, here are decompositions:

17 + 166781 = 166798
59 + 166739 = 166798
131 + 166667 = 166798
167 + 166631 = 166798
179 + 166619 = 166798
197 + 166601 = 166798
227 + 166571 = 166798
257 + 166541 = 166798

Showing the first eight; more decompositions exist.
