Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28756, here are decompositions:

3 + 28753 = 28756
5 + 28751 = 28756
53 + 28703 = 28756
59 + 28697 = 28756
107 + 28649 = 28756
113 + 28643 = 28756
137 + 28619 = 28756
149 + 28607 = 28756

Showing the first eight; more decompositions exist.
