Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505740, here are decompositions:

13 + 505727 = 505740
29 + 505711 = 505740
31 + 505709 = 505740
47 + 505693 = 505740
71 + 505669 = 505740
83 + 505657 = 505740
97 + 505643 = 505740
101 + 505639 = 505740

Showing the first eight; more decompositions exist.
