Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490396, here are decompositions:

3 + 490393 = 490396
29 + 490367 = 490396
83 + 490313 = 490396
113 + 490283 = 490396
149 + 490247 = 490396
173 + 490223 = 490396
227 + 490169 = 490396
293 + 490103 = 490396

Showing the first eight; more decompositions exist.
