Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475988, here are decompositions:

31 + 475957 = 475988
61 + 475927 = 475988
67 + 475921 = 475988
109 + 475879 = 475988
151 + 475837 = 475988
157 + 475831 = 475988
181 + 475807 = 475988
199 + 475789 = 475988

Showing the first eight; more decompositions exist.
