Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477818, here are decompositions:

7 + 477811 = 477818
79 + 477739 = 477818
97 + 477721 = 477818
181 + 477637 = 477818
199 + 477619 = 477818
241 + 477577 = 477818
307 + 477511 = 477818
349 + 477469 = 477818

Showing the first eight; more decompositions exist.
