Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490626, here are decompositions:

7 + 490619 = 490626
47 + 490579 = 490626
53 + 490573 = 490626
67 + 490559 = 490626
83 + 490543 = 490626
89 + 490537 = 490626
107 + 490519 = 490626
127 + 490499 = 490626

Showing the first eight; more decompositions exist.
