Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166422, here are decompositions:

5 + 166417 = 166422
13 + 166409 = 166422
19 + 166403 = 166422
23 + 166399 = 166422
29 + 166393 = 166422
59 + 166363 = 166422
71 + 166351 = 166422
73 + 166349 = 166422

Showing the first eight; more decompositions exist.
