Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487824, here are decompositions:

5 + 487819 = 487824
13 + 487811 = 487824
31 + 487793 = 487824
41 + 487783 = 487824
67 + 487757 = 487824
83 + 487741 = 487824
97 + 487727 = 487824
107 + 487717 = 487824

Showing the first eight; more decompositions exist.
