Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490838, here are decompositions:

67 + 490771 = 490838
97 + 490741 = 490838
211 + 490627 = 490838
379 + 490459 = 490838
421 + 490417 = 490838
499 + 490339 = 490838
571 + 490267 = 490838
631 + 490207 = 490838

Showing the first eight; more decompositions exist.
