Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28832, here are decompositions:

19 + 28813 = 28832
43 + 28789 = 28832
61 + 28771 = 28832
73 + 28759 = 28832
79 + 28753 = 28832
103 + 28729 = 28832
109 + 28723 = 28832
163 + 28669 = 28832

Showing the first eight; more decompositions exist.
