Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28016, here are decompositions:

19 + 27997 = 28016
73 + 27943 = 28016
97 + 27919 = 28016
193 + 27823 = 28016
199 + 27817 = 28016
223 + 27793 = 28016
277 + 27739 = 28016
283 + 27733 = 28016

Showing the first eight; more decompositions exist.
