Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490278, here are decompositions:

7 + 490271 = 490278
11 + 490267 = 490278
29 + 490249 = 490278
31 + 490247 = 490278
37 + 490241 = 490278
71 + 490207 = 490278
109 + 490169 = 490278
127 + 490151 = 490278

Showing the first eight; more decompositions exist.
