Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490632, here are decompositions:

5 + 490627 = 490632
13 + 490619 = 490632
41 + 490591 = 490632
53 + 490579 = 490632
59 + 490573 = 490632
61 + 490571 = 490632
73 + 490559 = 490632
83 + 490549 = 490632

Showing the first eight; more decompositions exist.
