Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28824, here are decompositions:

7 + 28817 = 28824
11 + 28813 = 28824
17 + 28807 = 28824
31 + 28793 = 28824
53 + 28771 = 28824
71 + 28753 = 28824
73 + 28751 = 28824
101 + 28723 = 28824

Showing the first eight; more decompositions exist.
