Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518566, here are decompositions:

23 + 518543 = 518566
137 + 518429 = 518566
149 + 518417 = 518566
179 + 518387 = 518566
239 + 518327 = 518566
317 + 518249 = 518566
359 + 518207 = 518566
443 + 518123 = 518566

Showing the first eight; more decompositions exist.
