Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490740, here are decompositions:

7 + 490733 = 490740
43 + 490697 = 490740
79 + 490661 = 490740
97 + 490643 = 490740
109 + 490631 = 490740
113 + 490627 = 490740
149 + 490591 = 490740
163 + 490577 = 490740

Showing the first eight; more decompositions exist.
