Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518554, here are decompositions:

11 + 518543 = 518554
83 + 518471 = 518554
107 + 518447 = 518554
137 + 518417 = 518554
167 + 518387 = 518554
227 + 518327 = 518554
263 + 518291 = 518554
293 + 518261 = 518554

Showing the first eight; more decompositions exist.
