Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490258, here are decompositions:

11 + 490247 = 490258
17 + 490241 = 490258
89 + 490169 = 490258
107 + 490151 = 490258
137 + 490121 = 490258
227 + 490031 = 490258
239 + 490019 = 490258
257 + 490001 = 490258

Showing the first eight; more decompositions exist.
