Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8256, here are decompositions:

13 + 8243 = 8256
19 + 8237 = 8256
23 + 8233 = 8256
37 + 8219 = 8256
47 + 8209 = 8256
89 + 8167 = 8256
109 + 8147 = 8256
139 + 8117 = 8256

Showing the first eight; more decompositions exist.
