Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166808, here are decompositions:

67 + 166741 = 166808
139 + 166669 = 166808
151 + 166657 = 166808
181 + 166627 = 166808
199 + 166609 = 166808
211 + 166597 = 166808
241 + 166567 = 166808
337 + 166471 = 166808

Showing the first eight; more decompositions exist.
