Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518588, here are decompositions:

67 + 518521 = 518588
79 + 518509 = 518588
157 + 518431 = 518588
199 + 518389 = 518588
277 + 518311 = 518588
349 + 518239 = 518588
379 + 518209 = 518588
397 + 518191 = 518588

Showing the first eight; more decompositions exist.
