Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27810, here are decompositions:

7 + 27803 = 27810
11 + 27799 = 27810
17 + 27793 = 27810
19 + 27791 = 27810
31 + 27779 = 27810
37 + 27773 = 27810
43 + 27767 = 27810
47 + 27763 = 27810

Showing the first eight; more decompositions exist.
