Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518028, here are decompositions:

11 + 518017 = 518028
29 + 517999 = 518028
37 + 517991 = 518028
47 + 517981 = 518028
61 + 517967 = 518028
79 + 517949 = 518028
97 + 517931 = 518028
101 + 517927 = 518028

Showing the first eight; more decompositions exist.
