Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495978, here are decompositions:

5 + 495973 = 495978
11 + 495967 = 495978
19 + 495959 = 495978
31 + 495947 = 495978
47 + 495931 = 495978
79 + 495899 = 495978
101 + 495877 = 495978
127 + 495851 = 495978

Showing the first eight; more decompositions exist.
