Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518214, here are decompositions:

5 + 518209 = 518214
7 + 518207 = 518214
23 + 518191 = 518214
43 + 518171 = 518214
61 + 518153 = 518214
83 + 518131 = 518214
101 + 518113 = 518214
113 + 518101 = 518214

Showing the first eight; more decompositions exist.
