Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28644, here are decompositions:

13 + 28631 = 28644
17 + 28627 = 28644
23 + 28621 = 28644
37 + 28607 = 28644
41 + 28603 = 28644
47 + 28597 = 28644
53 + 28591 = 28644
71 + 28573 = 28644

Showing the first eight; more decompositions exist.
