Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505746, here are decompositions:

19 + 505727 = 505746
37 + 505709 = 505746
53 + 505693 = 505746
83 + 505663 = 505746
89 + 505657 = 505746
103 + 505643 = 505746
107 + 505639 = 505746
113 + 505633 = 505746

Showing the first eight; more decompositions exist.
