Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505722, here are decompositions:

11 + 505711 = 505722
13 + 505709 = 505722
29 + 505693 = 505722
31 + 505691 = 505722
53 + 505669 = 505722
59 + 505663 = 505722
79 + 505643 = 505722
83 + 505639 = 505722

Showing the first eight; more decompositions exist.
