Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27968, here are decompositions:

7 + 27961 = 27968
67 + 27901 = 27968
151 + 27817 = 27968
229 + 27739 = 27968
271 + 27697 = 27968
277 + 27691 = 27968
337 + 27631 = 27968
439 + 27529 = 27968

Showing the first eight; more decompositions exist.
