Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518406, here are decompositions:

17 + 518389 = 518406
19 + 518387 = 518406
79 + 518327 = 518406
107 + 518299 = 518406
157 + 518249 = 518406
167 + 518239 = 518406
173 + 518233 = 518406
197 + 518209 = 518406

Showing the first eight; more decompositions exist.
