Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490390, here are decompositions:

23 + 490367 = 490390
107 + 490283 = 490390
113 + 490277 = 490390
149 + 490241 = 490390
167 + 490223 = 490390
239 + 490151 = 490390
269 + 490121 = 490390
293 + 490097 = 490390

Showing the first eight; more decompositions exist.
