Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477138, here are decompositions:

7 + 477131 = 477138
47 + 477091 = 477138
61 + 477077 = 477138
107 + 477031 = 477138
127 + 477011 = 477138
149 + 476989 = 477138
157 + 476981 = 477138
227 + 476911 = 477138

Showing the first eight; more decompositions exist.
