Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 504990, here are decompositions:

7 + 504983 = 504990
23 + 504967 = 504990
37 + 504953 = 504990
43 + 504947 = 504990
47 + 504943 = 504990
53 + 504937 = 504990
61 + 504929 = 504990
89 + 504901 = 504990

Showing the first eight; more decompositions exist.
