Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28966, here are decompositions:

5 + 28961 = 28966
17 + 28949 = 28966
107 + 28859 = 28966
149 + 28817 = 28966
173 + 28793 = 28966
263 + 28703 = 28966
269 + 28697 = 28966
317 + 28649 = 28966

Showing the first eight; more decompositions exist.
