Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518354, here are decompositions:

13 + 518341 = 518354
43 + 518311 = 518354
163 + 518191 = 518354
223 + 518131 = 518354
241 + 518113 = 518354
271 + 518083 = 518354
307 + 518047 = 518354
337 + 518017 = 518354

Showing the first eight; more decompositions exist.
