Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518716, here are decompositions:

17 + 518699 = 518716
59 + 518657 = 518716
137 + 518579 = 518716
173 + 518543 = 518716
269 + 518447 = 518716
389 + 518327 = 518716
467 + 518249 = 518716
479 + 518237 = 518716

Showing the first eight; more decompositions exist.
