Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27820, here are decompositions:

3 + 27817 = 27820
11 + 27809 = 27820
17 + 27803 = 27820
29 + 27791 = 27820
41 + 27779 = 27820
47 + 27773 = 27820
53 + 27767 = 27820
71 + 27749 = 27820

Showing the first eight; more decompositions exist.
