Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477822, here are decompositions:

11 + 477811 = 477822
13 + 477809 = 477822
31 + 477791 = 477822
53 + 477769 = 477822
83 + 477739 = 477822
101 + 477721 = 477822
151 + 477671 = 477822
199 + 477623 = 477822

Showing the first eight; more decompositions exist.
