Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487066, here are decompositions:

17 + 487049 = 487066
53 + 487013 = 487066
59 + 487007 = 487066
89 + 486977 = 487066
137 + 486929 = 487066
197 + 486869 = 487066
227 + 486839 = 487066
233 + 486833 = 487066

Showing the first eight; more decompositions exist.
