Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168256, here are decompositions:

3 + 168253 = 168256
29 + 168227 = 168256
59 + 168197 = 168256
113 + 168143 = 168256
167 + 168089 = 168256
173 + 168083 = 168256
227 + 168029 = 168256
233 + 168023 = 168256

Showing the first eight; more decompositions exist.
