Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490664, here are decompositions:

3 + 490661 = 490664
37 + 490627 = 490664
73 + 490591 = 490664
127 + 490537 = 490664
211 + 490453 = 490664
271 + 490393 = 490664
397 + 490267 = 490664
457 + 490207 = 490664

Showing the first eight; more decompositions exist.
