Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166546, here are decompositions:

5 + 166541 = 166546
59 + 166487 = 166546
89 + 166457 = 166546
137 + 166409 = 166546
197 + 166349 = 166546
227 + 166319 = 166546
257 + 166289 = 166546
389 + 166157 = 166546

Showing the first eight; more decompositions exist.
