Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487828, here are decompositions:

17 + 487811 = 487828
59 + 487769 = 487828
71 + 487757 = 487828
101 + 487727 = 487828
137 + 487691 = 487828
179 + 487649 = 487828
191 + 487637 = 487828
227 + 487601 = 487828

Showing the first eight; more decompositions exist.
