Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485840, here are decompositions:

7 + 485833 = 485840
13 + 485827 = 485840
109 + 485731 = 485840
139 + 485701 = 485840
151 + 485689 = 485840
193 + 485647 = 485840
331 + 485509 = 485840
457 + 485383 = 485840

Showing the first eight; more decompositions exist.
