Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490826, here are decompositions:

43 + 490783 = 490826
163 + 490663 = 490826
199 + 490627 = 490826
277 + 490549 = 490826
283 + 490543 = 490826
307 + 490519 = 490826
367 + 490459 = 490826
373 + 490453 = 490826

Showing the first eight; more decompositions exist.
