Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166568, here are decompositions:

7 + 166561 = 166568
97 + 166471 = 166568
139 + 166429 = 166568
151 + 166417 = 166568
211 + 166357 = 166568
271 + 166297 = 166568
331 + 166237 = 166568
349 + 166219 = 166568

Showing the first eight; more decompositions exist.
