Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490722, here are decompositions:

59 + 490663 = 490722
61 + 490661 = 490722
79 + 490643 = 490722
103 + 490619 = 490722
131 + 490591 = 490722
149 + 490573 = 490722
151 + 490571 = 490722
163 + 490559 = 490722

Showing the first eight; more decompositions exist.
