Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505724, here are decompositions:

13 + 505711 = 505724
31 + 505693 = 505724
61 + 505663 = 505724
67 + 505657 = 505724
151 + 505573 = 505724
211 + 505513 = 505724
223 + 505501 = 505724
277 + 505447 = 505724

Showing the first eight; more decompositions exist.
