Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518524, here are decompositions:

3 + 518521 = 518524
53 + 518471 = 518524
107 + 518417 = 518524
113 + 518411 = 518524
137 + 518387 = 518524
197 + 518327 = 518524
233 + 518291 = 518524
263 + 518261 = 518524

Showing the first eight; more decompositions exist.
