Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10256, here are decompositions:

3 + 10253 = 10256
13 + 10243 = 10256
79 + 10177 = 10256
97 + 10159 = 10256
157 + 10099 = 10256
163 + 10093 = 10256
283 + 9973 = 10256
307 + 9949 = 10256

Showing the first eight; more decompositions exist.
