Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485720, here are decompositions:

3 + 485717 = 485720
19 + 485701 = 485720
31 + 485689 = 485720
73 + 485647 = 485720
127 + 485593 = 485720
211 + 485509 = 485720
223 + 485497 = 485720
241 + 485479 = 485720

Showing the first eight; more decompositions exist.
