Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490650, here are decompositions:

7 + 490643 = 490650
19 + 490631 = 490650
23 + 490627 = 490650
31 + 490619 = 490650
59 + 490591 = 490650
71 + 490579 = 490650
73 + 490577 = 490650
79 + 490571 = 490650

Showing the first eight; more decompositions exist.
