Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166258, here are decompositions:

11 + 166247 = 166258
89 + 166169 = 166258
101 + 166157 = 166258
107 + 166151 = 166258
227 + 166031 = 166258
311 + 165947 = 166258
317 + 165941 = 166258
401 + 165857 = 166258

Showing the first eight; more decompositions exist.
