Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518432, here are decompositions:

3 + 518429 = 518432
43 + 518389 = 518432
193 + 518239 = 518432
199 + 518233 = 518432
223 + 518209 = 518432
241 + 518191 = 518432
331 + 518101 = 518432
349 + 518083 = 518432

Showing the first eight; more decompositions exist.
