Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28876, here are decompositions:

5 + 28871 = 28876
17 + 28859 = 28876
59 + 28817 = 28876
83 + 28793 = 28876
173 + 28703 = 28876
179 + 28697 = 28876
227 + 28649 = 28876
233 + 28643 = 28876

Showing the first eight; more decompositions exist.
