Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505050, here are decompositions:

17 + 505033 = 505050
19 + 505031 = 505050
23 + 505027 = 505050
59 + 504991 = 505050
61 + 504989 = 505050
67 + 504983 = 505050
83 + 504967 = 505050
97 + 504953 = 505050

Showing the first eight; more decompositions exist.
