Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505776, here are decompositions:

13 + 505763 = 505776
17 + 505759 = 505776
67 + 505709 = 505776
83 + 505693 = 505776
107 + 505669 = 505776
113 + 505663 = 505776
137 + 505639 = 505776
157 + 505619 = 505776

Showing the first eight; more decompositions exist.
