Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518488, here are decompositions:

17 + 518471 = 518488
41 + 518447 = 518488
59 + 518429 = 518488
71 + 518417 = 518488
101 + 518387 = 518488
197 + 518291 = 518488
227 + 518261 = 518488
239 + 518249 = 518488

Showing the first eight; more decompositions exist.
