Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475978, here are decompositions:

5 + 475973 = 475978
71 + 475907 = 475978
89 + 475889 = 475978
101 + 475877 = 475978
137 + 475841 = 475978
227 + 475751 = 475978
257 + 475721 = 475978
281 + 475697 = 475978

Showing the first eight; more decompositions exist.
