Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518222, here are decompositions:

13 + 518209 = 518222
31 + 518191 = 518222
43 + 518179 = 518222
109 + 518113 = 518222
139 + 518083 = 518222
163 + 518059 = 518222
223 + 517999 = 518222
241 + 517981 = 518222

Showing the first eight; more decompositions exist.
