Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518392, here are decompositions:

3 + 518389 = 518392
5 + 518387 = 518392
101 + 518291 = 518392
131 + 518261 = 518392
233 + 518159 = 518392
239 + 518153 = 518392
263 + 518129 = 518392
269 + 518123 = 518392

Showing the first eight; more decompositions exist.
