Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38828, here are decompositions:

7 + 38821 = 38828
37 + 38791 = 38828
61 + 38767 = 38828
79 + 38749 = 38828
151 + 38677 = 38828
157 + 38671 = 38828
199 + 38629 = 38828
271 + 38557 = 38828

Showing the first eight; more decompositions exist.
