Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505770, here are decompositions:

7 + 505763 = 505770
11 + 505759 = 505770
43 + 505727 = 505770
59 + 505711 = 505770
61 + 505709 = 505770
79 + 505691 = 505770
101 + 505669 = 505770
107 + 505663 = 505770

Showing the first eight; more decompositions exist.
