Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490458, here are decompositions:

5 + 490453 = 490458
37 + 490421 = 490458
41 + 490417 = 490458
149 + 490309 = 490458
181 + 490277 = 490458
191 + 490267 = 490458
211 + 490247 = 490458
251 + 490207 = 490458

Showing the first eight; more decompositions exist.
