Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490646, here are decompositions:

3 + 490643 = 490646
19 + 490627 = 490646
67 + 490579 = 490646
73 + 490573 = 490646
97 + 490549 = 490646
103 + 490543 = 490646
109 + 490537 = 490646
127 + 490519 = 490646

Showing the first eight; more decompositions exist.
