Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518378, here are decompositions:

37 + 518341 = 518378
67 + 518311 = 518378
79 + 518299 = 518378
139 + 518239 = 518378
199 + 518179 = 518378
241 + 518137 = 518378
277 + 518101 = 518378
331 + 518047 = 518378

Showing the first eight; more decompositions exist.
