Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505086, here are decompositions:

13 + 505073 = 505086
19 + 505067 = 505086
37 + 505049 = 505086
53 + 505033 = 505086
59 + 505027 = 505086
97 + 504989 = 505086
103 + 504983 = 505086
139 + 504947 = 505086

Showing the first eight; more decompositions exist.
