Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490408, here are decompositions:

41 + 490367 = 490408
131 + 490277 = 490408
137 + 490271 = 490408
167 + 490241 = 490408
239 + 490169 = 490408
257 + 490151 = 490408
311 + 490097 = 490408
389 + 490019 = 490408

Showing the first eight; more decompositions exist.
