Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166222, here are decompositions:

3 + 166219 = 166222
53 + 166169 = 166222
71 + 166151 = 166222
179 + 166043 = 166222
191 + 166031 = 166222
239 + 165983 = 166222
281 + 165941 = 166222
389 + 165833 = 166222

Showing the first eight; more decompositions exist.
