Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485844, here are decompositions:

11 + 485833 = 485844
13 + 485831 = 485844
17 + 485827 = 485844
67 + 485777 = 485844
113 + 485731 = 485844
127 + 485717 = 485844
173 + 485671 = 485844
197 + 485647 = 485844

Showing the first eight; more decompositions exist.
