Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486828, here are decompositions:

7 + 486821 = 486828
11 + 486817 = 486828
31 + 486797 = 486828
47 + 486781 = 486828
59 + 486769 = 486828
61 + 486767 = 486828
71 + 486757 = 486828
107 + 486721 = 486828

Showing the first eight; more decompositions exist.
