Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475986, here are decompositions:

13 + 475973 = 475986
29 + 475957 = 475986
53 + 475933 = 475986
59 + 475927 = 475986
79 + 475907 = 475986
83 + 475903 = 475986
89 + 475897 = 475986
97 + 475889 = 475986

Showing the first eight; more decompositions exist.
