Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27816, here are decompositions:

7 + 27809 = 27816
13 + 27803 = 27816
17 + 27799 = 27816
23 + 27793 = 27816
37 + 27779 = 27816
43 + 27773 = 27816
53 + 27763 = 27816
67 + 27749 = 27816

Showing the first eight; more decompositions exist.
