Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28888, here are decompositions:

17 + 28871 = 28888
29 + 28859 = 28888
71 + 28817 = 28888
137 + 28751 = 28888
191 + 28697 = 28888
227 + 28661 = 28888
239 + 28649 = 28888
257 + 28631 = 28888

Showing the first eight; more decompositions exist.
