Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16386, here are decompositions:

5 + 16381 = 16386
17 + 16369 = 16386
23 + 16363 = 16386
37 + 16349 = 16386
47 + 16339 = 16386
53 + 16333 = 16386
67 + 16319 = 16386
113 + 16273 = 16386

Showing the first eight; more decompositions exist.
