Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485820, here are decompositions:

43 + 485777 = 485820
67 + 485753 = 485820
89 + 485731 = 485820
103 + 485717 = 485820
131 + 485689 = 485820
149 + 485671 = 485820
163 + 485657 = 485820
173 + 485647 = 485820

Showing the first eight; more decompositions exist.
