Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505772, here are decompositions:

13 + 505759 = 505772
61 + 505711 = 505772
79 + 505693 = 505772
103 + 505669 = 505772
109 + 505663 = 505772
139 + 505633 = 505772
199 + 505573 = 505772
271 + 505501 = 505772

Showing the first eight; more decompositions exist.
