Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666146, here are decompositions:

53 + 8666093 = 8666146
89 + 8666057 = 8666146
173 + 8665973 = 8666146
179 + 8665967 = 8666146
197 + 8665949 = 8666146
233 + 8665913 = 8666146
257 + 8665889 = 8666146
347 + 8665799 = 8666146

Showing the first eight; more decompositions exist.
