Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16516, here are decompositions:

23 + 16493 = 16516
29 + 16487 = 16516
83 + 16433 = 16516
89 + 16427 = 16516
167 + 16349 = 16516
197 + 16319 = 16516
263 + 16253 = 16516
293 + 16223 = 16516

Showing the first eight; more decompositions exist.
