Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166368, here are decompositions:

5 + 166363 = 166368
11 + 166357 = 166368
17 + 166351 = 166368
19 + 166349 = 166368
67 + 166301 = 166368
71 + 166297 = 166368
79 + 166289 = 166368
109 + 166259 = 166368

Showing the first eight; more decompositions exist.
