Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28064, here are decompositions:

7 + 28057 = 28064
13 + 28051 = 28064
37 + 28027 = 28064
67 + 27997 = 28064
97 + 27967 = 28064
103 + 27961 = 28064
163 + 27901 = 28064
181 + 27883 = 28064

Showing the first eight; more decompositions exist.
