Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490634, here are decompositions:

3 + 490631 = 490634
7 + 490627 = 490634
43 + 490591 = 490634
61 + 490573 = 490634
97 + 490537 = 490634
181 + 490453 = 490634
241 + 490393 = 490634
367 + 490267 = 490634

Showing the first eight; more decompositions exist.
