Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477820, here are decompositions:

11 + 477809 = 477820
23 + 477797 = 477820
29 + 477791 = 477820
53 + 477767 = 477820
89 + 477731 = 477820
149 + 477671 = 477820
197 + 477623 = 477820
227 + 477593 = 477820

Showing the first eight; more decompositions exist.
