Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166508, here are decompositions:

37 + 166471 = 166508
79 + 166429 = 166508
109 + 166399 = 166508
151 + 166357 = 166508
157 + 166351 = 166508
211 + 166297 = 166508
271 + 166237 = 166508
409 + 166099 = 166508

Showing the first eight; more decompositions exist.
