Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39968, here are decompositions:

31 + 39937 = 39968
67 + 39901 = 39968
127 + 39841 = 39968
139 + 39829 = 39968
199 + 39769 = 39968
241 + 39727 = 39968
337 + 39631 = 39968
349 + 39619 = 39968

Showing the first eight; more decompositions exist.
