Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166380, here are decompositions:

17 + 166363 = 166380
23 + 166357 = 166380
29 + 166351 = 166380
31 + 166349 = 166380
61 + 166319 = 166380
79 + 166301 = 166380
83 + 166297 = 166380
107 + 166273 = 166380

Showing the first eight; more decompositions exist.
