Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515716, here are decompositions:

23 + 515693 = 515716
29 + 515687 = 515716
53 + 515663 = 515716
137 + 515579 = 515716
197 + 515519 = 515716
239 + 515477 = 515716
347 + 515369 = 515716
359 + 515357 = 515716

Showing the first eight; more decompositions exist.
