Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4256, here are decompositions:

3 + 4253 = 4256
13 + 4243 = 4256
37 + 4219 = 4256
79 + 4177 = 4256
97 + 4159 = 4256
103 + 4153 = 4256
127 + 4129 = 4256
157 + 4099 = 4256

Showing the first eight; more decompositions exist.
