Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28834, here are decompositions:

17 + 28817 = 28834
41 + 28793 = 28834
83 + 28751 = 28834
131 + 28703 = 28834
137 + 28697 = 28834
173 + 28661 = 28834
191 + 28643 = 28834
227 + 28607 = 28834

Showing the first eight; more decompositions exist.
