Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518382, here are decompositions:

41 + 518341 = 518382
71 + 518311 = 518382
83 + 518299 = 518382
149 + 518233 = 518382
173 + 518209 = 518382
191 + 518191 = 518382
211 + 518171 = 518382
223 + 518159 = 518382

Showing the first eight; more decompositions exist.
