Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505566, here are decompositions:

7 + 505559 = 505566
29 + 505537 = 505566
43 + 505523 = 505566
53 + 505513 = 505566
73 + 505493 = 505566
97 + 505469 = 505566
107 + 505459 = 505566
137 + 505429 = 505566

Showing the first eight; more decompositions exist.
