Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518348, here are decompositions:

7 + 518341 = 518348
37 + 518311 = 518348
109 + 518239 = 518348
139 + 518209 = 518348
157 + 518191 = 518348
211 + 518137 = 518348
331 + 518017 = 518348
349 + 517999 = 518348

Showing the first eight; more decompositions exist.
