Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33820, here are decompositions:

11 + 33809 = 33820
23 + 33797 = 33820
29 + 33791 = 33820
47 + 33773 = 33820
53 + 33767 = 33820
71 + 33749 = 33820
107 + 33713 = 33820
173 + 33647 = 33820

Showing the first eight; more decompositions exist.
