Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515984, here are decompositions:

43 + 515941 = 515984
61 + 515923 = 515984
67 + 515917 = 515984
97 + 515887 = 515984
127 + 515857 = 515984
181 + 515803 = 515984
211 + 515773 = 515984
223 + 515761 = 515984

Showing the first eight; more decompositions exist.
