Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505008, here are decompositions:

17 + 504991 = 505008
19 + 504989 = 505008
41 + 504967 = 505008
61 + 504947 = 505008
71 + 504937 = 505008
79 + 504929 = 505008
107 + 504901 = 505008
131 + 504877 = 505008

Showing the first eight; more decompositions exist.
