Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28726, here are decompositions:

3 + 28723 = 28726
23 + 28703 = 28726
29 + 28697 = 28726
83 + 28643 = 28726
107 + 28619 = 28726
167 + 28559 = 28726
179 + 28547 = 28726
227 + 28499 = 28726

Showing the first eight; more decompositions exist.
