Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505940, here are decompositions:

13 + 505927 = 505940
73 + 505867 = 505940
163 + 505777 = 505940
181 + 505759 = 505940
229 + 505711 = 505940
271 + 505669 = 505940
277 + 505663 = 505940
283 + 505657 = 505940

Showing the first eight; more decompositions exist.
