Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490850, here are decompositions:

13 + 490837 = 490850
67 + 490783 = 490850
79 + 490771 = 490850
109 + 490741 = 490850
223 + 490627 = 490850
271 + 490579 = 490850
277 + 490573 = 490850
307 + 490543 = 490850

Showing the first eight; more decompositions exist.
