Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78518, here are decompositions:

7 + 78511 = 78518
31 + 78487 = 78518
79 + 78439 = 78518
151 + 78367 = 78518
211 + 78307 = 78518
241 + 78277 = 78518
277 + 78241 = 78518
379 + 78139 = 78518

Showing the first eight; more decompositions exist.
