Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477828, here are decompositions:

5 + 477823 = 477828
7 + 477821 = 477828
17 + 477811 = 477828
19 + 477809 = 477828
31 + 477797 = 477828
37 + 477791 = 477828
59 + 477769 = 477828
61 + 477767 = 477828

Showing the first eight; more decompositions exist.
