Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166606, here are decompositions:

3 + 166603 = 166606
5 + 166601 = 166606
149 + 166457 = 166606
197 + 166409 = 166606
257 + 166349 = 166606
317 + 166289 = 166606
347 + 166259 = 166606
359 + 166247 = 166606

Showing the first eight; more decompositions exist.
