Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477220, here are decompositions:

11 + 477209 = 477220
71 + 477149 = 477220
89 + 477131 = 477220
173 + 477047 = 477220
239 + 476981 = 477220
389 + 476831 = 477220
461 + 476759 = 477220
467 + 476753 = 477220

Showing the first eight; more decompositions exist.
