Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490768, here are decompositions:

71 + 490697 = 490768
107 + 490661 = 490768
137 + 490631 = 490768
149 + 490619 = 490768
191 + 490577 = 490768
197 + 490571 = 490768
227 + 490541 = 490768
269 + 490499 = 490768

Showing the first eight; more decompositions exist.
