Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518342, here are decompositions:

31 + 518311 = 518342
43 + 518299 = 518342
103 + 518239 = 518342
109 + 518233 = 518342
151 + 518191 = 518342
163 + 518179 = 518342
211 + 518131 = 518342
229 + 518113 = 518342

Showing the first eight; more decompositions exist.
