Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28882, here are decompositions:

3 + 28879 = 28882
11 + 28871 = 28882
23 + 28859 = 28882
89 + 28793 = 28882
131 + 28751 = 28882
179 + 28703 = 28882
233 + 28649 = 28882
239 + 28643 = 28882

Showing the first eight; more decompositions exist.
