Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166198, here are decompositions:

29 + 166169 = 166198
41 + 166157 = 166198
47 + 166151 = 166198
167 + 166031 = 166198
251 + 165947 = 166198
257 + 165941 = 166198
311 + 165887 = 166198
419 + 165779 = 166198

Showing the first eight; more decompositions exist.
