Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505026, here are decompositions:

37 + 504989 = 505026
43 + 504983 = 505026
59 + 504967 = 505026
73 + 504953 = 505026
79 + 504947 = 505026
83 + 504943 = 505026
89 + 504937 = 505026
97 + 504929 = 505026

Showing the first eight; more decompositions exist.
