Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518358, here are decompositions:

17 + 518341 = 518358
31 + 518327 = 518358
47 + 518311 = 518358
59 + 518299 = 518358
67 + 518291 = 518358
97 + 518261 = 518358
109 + 518249 = 518358
149 + 518209 = 518358

Showing the first eight; more decompositions exist.
