Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39828, here are decompositions:

7 + 39821 = 39828
29 + 39799 = 39828
37 + 39791 = 39828
59 + 39769 = 39828
67 + 39761 = 39828
79 + 39749 = 39828
101 + 39727 = 39828
109 + 39719 = 39828

Showing the first eight; more decompositions exist.
