Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166396, here are decompositions:

3 + 166393 = 166396
47 + 166349 = 166396
107 + 166289 = 166396
137 + 166259 = 166396
149 + 166247 = 166396
227 + 166169 = 166396
239 + 166157 = 166396
353 + 166043 = 166396

Showing the first eight; more decompositions exist.
