Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490666, here are decompositions:

3 + 490663 = 490666
5 + 490661 = 490666
23 + 490643 = 490666
47 + 490619 = 490666
89 + 490577 = 490666
107 + 490559 = 490666
167 + 490499 = 490666
173 + 490493 = 490666

Showing the first eight; more decompositions exist.
