Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515940, here are decompositions:

11 + 515929 = 515940
17 + 515923 = 515940
23 + 515917 = 515940
53 + 515887 = 515940
67 + 515873 = 515940
79 + 515861 = 515940
83 + 515857 = 515940
97 + 515843 = 515940

Showing the first eight; more decompositions exist.
