Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490670, here are decompositions:

7 + 490663 = 490670
43 + 490627 = 490670
79 + 490591 = 490670
97 + 490573 = 490670
127 + 490543 = 490670
151 + 490519 = 490670
211 + 490459 = 490670
277 + 490393 = 490670

Showing the first eight; more decompositions exist.
