Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477982, here are decompositions:

5 + 477977 = 477982
41 + 477941 = 477982
83 + 477899 = 477982
101 + 477881 = 477982
173 + 477809 = 477982
191 + 477791 = 477982
251 + 477731 = 477982
311 + 477671 = 477982

Showing the first eight; more decompositions exist.
