Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477440, here are decompositions:

31 + 477409 = 477440
79 + 477361 = 477440
127 + 477313 = 477440
163 + 477277 = 477440
181 + 477259 = 477440
211 + 477229 = 477440
277 + 477163 = 477440
349 + 477091 = 477440

Showing the first eight; more decompositions exist.
