Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490536, here are decompositions:

17 + 490519 = 490536
37 + 490499 = 490536
43 + 490493 = 490536
73 + 490463 = 490536
83 + 490453 = 490536
197 + 490339 = 490536
223 + 490313 = 490536
227 + 490309 = 490536

Showing the first eight; more decompositions exist.
