Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490724, here are decompositions:

61 + 490663 = 490724
97 + 490627 = 490724
151 + 490573 = 490724
181 + 490543 = 490724
271 + 490453 = 490724
307 + 490417 = 490724
331 + 490393 = 490724
457 + 490267 = 490724

Showing the first eight; more decompositions exist.
