Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518078, here are decompositions:

19 + 518059 = 518078
31 + 518047 = 518078
61 + 518017 = 518078
79 + 517999 = 518078
97 + 517981 = 518078
151 + 517927 = 518078
331 + 517747 = 518078
349 + 517729 = 518078

Showing the first eight; more decompositions exist.
