Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490690, here are decompositions:

29 + 490661 = 490690
47 + 490643 = 490690
59 + 490631 = 490690
71 + 490619 = 490690
113 + 490577 = 490690
131 + 490559 = 490690
149 + 490541 = 490690
191 + 490499 = 490690

Showing the first eight; more decompositions exist.
