Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491086, here are decompositions:

3 + 491083 = 491086
5 + 491081 = 491086
47 + 491039 = 491086
83 + 491003 = 491086
137 + 490949 = 491086
149 + 490937 = 491086
173 + 490913 = 491086
227 + 490859 = 491086

Showing the first eight; more decompositions exist.
