Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518564, here are decompositions:

31 + 518533 = 518564
43 + 518521 = 518564
97 + 518467 = 518564
223 + 518341 = 518564
331 + 518233 = 518564
373 + 518191 = 518564
433 + 518131 = 518564
463 + 518101 = 518564

Showing the first eight; more decompositions exist.
