Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490558, here are decompositions:

17 + 490541 = 490558
59 + 490499 = 490558
137 + 490421 = 490558
191 + 490367 = 490558
281 + 490277 = 490558
311 + 490247 = 490558
317 + 490241 = 490558
389 + 490169 = 490558

Showing the first eight; more decompositions exist.
