Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018186, here are decompositions:

89 + 1018097 = 1018186
167 + 1018019 = 1018186
179 + 1018007 = 1018186
227 + 1017959 = 1018186
233 + 1017953 = 1018186
263 + 1017923 = 1018186
359 + 1017827 = 1018186
467 + 1017719 = 1018186

Showing the first eight; more decompositions exist.
