Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166446, here are decompositions:

17 + 166429 = 166446
29 + 166417 = 166446
37 + 166409 = 166446
43 + 166403 = 166446
47 + 166399 = 166446
53 + 166393 = 166446
83 + 166363 = 166446
89 + 166357 = 166446

Showing the first eight; more decompositions exist.
