Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13256, here are decompositions:

7 + 13249 = 13256
37 + 13219 = 13256
73 + 13183 = 13256
79 + 13177 = 13256
97 + 13159 = 13256
109 + 13147 = 13256
157 + 13099 = 13256
163 + 13093 = 13256

Showing the first eight; more decompositions exist.
