Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490550, here are decompositions:

7 + 490543 = 490550
13 + 490537 = 490550
31 + 490519 = 490550
97 + 490453 = 490550
157 + 490393 = 490550
211 + 490339 = 490550
241 + 490309 = 490550
283 + 490267 = 490550

Showing the first eight; more decompositions exist.
