Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28636, here are decompositions:

5 + 28631 = 28636
17 + 28619 = 28636
29 + 28607 = 28636
89 + 28547 = 28636
137 + 28499 = 28636
173 + 28463 = 28636
197 + 28439 = 28636
227 + 28409 = 28636

Showing the first eight; more decompositions exist.
