Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3256, here are decompositions:

3 + 3253 = 3256
5 + 3251 = 3256
47 + 3209 = 3256
53 + 3203 = 3256
89 + 3167 = 3256
137 + 3119 = 3256
167 + 3089 = 3256
173 + 3083 = 3256

Showing the first eight; more decompositions exist.
