Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501978, here are decompositions:

7 + 501971 = 501978
11 + 501967 = 501978
31 + 501947 = 501978
47 + 501931 = 501978
67 + 501911 = 501978
89 + 501889 = 501978
137 + 501841 = 501978
149 + 501829 = 501978

Showing the first eight; more decompositions exist.
