Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166366, here are decompositions:

3 + 166363 = 166366
17 + 166349 = 166366
47 + 166319 = 166366
107 + 166259 = 166366
197 + 166169 = 166366
353 + 166013 = 166366
383 + 165983 = 166366
419 + 165947 = 166366

Showing the first eight; more decompositions exist.
