Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68256, here are decompositions:

17 + 68239 = 68256
29 + 68227 = 68256
37 + 68219 = 68256
43 + 68213 = 68256
47 + 68209 = 68256
109 + 68147 = 68256
157 + 68099 = 68256
197 + 68059 = 68256

Showing the first eight; more decompositions exist.
