Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518468, here are decompositions:

37 + 518431 = 518468
79 + 518389 = 518468
127 + 518341 = 518468
157 + 518311 = 518468
229 + 518239 = 518468
277 + 518191 = 518468
331 + 518137 = 518468
337 + 518131 = 518468

Showing the first eight; more decompositions exist.
