Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27804, here are decompositions:

5 + 27799 = 27804
11 + 27793 = 27804
13 + 27791 = 27804
31 + 27773 = 27804
37 + 27767 = 27804
41 + 27763 = 27804
53 + 27751 = 27804
61 + 27743 = 27804

Showing the first eight; more decompositions exist.
