Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38820, here are decompositions:

17 + 38803 = 38820
29 + 38791 = 38820
37 + 38783 = 38820
53 + 38767 = 38820
71 + 38749 = 38820
73 + 38747 = 38820
83 + 38737 = 38820
97 + 38723 = 38820

Showing the first eight; more decompositions exist.
