Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505730, here are decompositions:

3 + 505727 = 505730
19 + 505711 = 505730
37 + 505693 = 505730
61 + 505669 = 505730
67 + 505663 = 505730
73 + 505657 = 505730
97 + 505633 = 505730
157 + 505573 = 505730

Showing the first eight; more decompositions exist.
