Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475812, here are decompositions:

5 + 475807 = 475812
19 + 475793 = 475812
23 + 475789 = 475812
53 + 475759 = 475812
59 + 475753 = 475812
61 + 475751 = 475812
83 + 475729 = 475812
131 + 475681 = 475812

Showing the first eight; more decompositions exist.
