Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490522, here are decompositions:

3 + 490519 = 490522
23 + 490499 = 490522
29 + 490493 = 490522
41 + 490481 = 490522
59 + 490463 = 490522
101 + 490421 = 490522
239 + 490283 = 490522
251 + 490271 = 490522

Showing the first eight; more decompositions exist.
