Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477988, here are decompositions:

11 + 477977 = 477988
41 + 477947 = 477988
47 + 477941 = 477988
89 + 477899 = 477988
107 + 477881 = 477988
131 + 477857 = 477988
149 + 477839 = 477988
167 + 477821 = 477988

Showing the first eight; more decompositions exist.
