Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28014, here are decompositions:

13 + 28001 = 28014
17 + 27997 = 28014
31 + 27983 = 28014
47 + 27967 = 28014
53 + 27961 = 28014
61 + 27953 = 28014
67 + 27947 = 28014
71 + 27943 = 28014

Showing the first eight; more decompositions exist.
