Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490404, here are decompositions:

11 + 490393 = 490404
37 + 490367 = 490404
127 + 490277 = 490404
137 + 490267 = 490404
157 + 490247 = 490404
163 + 490241 = 490404
181 + 490223 = 490404
197 + 490207 = 490404

Showing the first eight; more decompositions exist.
