Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166574, here are decompositions:

3 + 166571 = 166574
7 + 166567 = 166574
13 + 166561 = 166574
103 + 166471 = 166574
157 + 166417 = 166574
181 + 166393 = 166574
211 + 166363 = 166574
223 + 166351 = 166574

Showing the first eight; more decompositions exist.
