Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486820, here are decompositions:

3 + 486817 = 486820
23 + 486797 = 486820
53 + 486767 = 486820
107 + 486713 = 486820
137 + 486683 = 486820
149 + 486671 = 486820
167 + 486653 = 486820
179 + 486641 = 486820

Showing the first eight; more decompositions exist.
