Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490684, here are decompositions:

23 + 490661 = 490684
41 + 490643 = 490684
53 + 490631 = 490684
107 + 490577 = 490684
113 + 490571 = 490684
191 + 490493 = 490684
263 + 490421 = 490684
317 + 490367 = 490684

Showing the first eight; more decompositions exist.
