Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490630, here are decompositions:

3 + 490627 = 490630
11 + 490619 = 490630
53 + 490577 = 490630
59 + 490571 = 490630
71 + 490559 = 490630
89 + 490541 = 490630
131 + 490499 = 490630
137 + 490493 = 490630

Showing the first eight; more decompositions exist.
