Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490806, here are decompositions:

23 + 490783 = 490806
37 + 490769 = 490806
73 + 490733 = 490806
109 + 490697 = 490806
163 + 490643 = 490806
179 + 490627 = 490806
227 + 490579 = 490806
229 + 490577 = 490806

Showing the first eight; more decompositions exist.
