Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72256, here are decompositions:

3 + 72253 = 72256
5 + 72251 = 72256
29 + 72227 = 72256
83 + 72173 = 72256
89 + 72167 = 72256
167 + 72089 = 72256
179 + 72077 = 72256
257 + 71999 = 72256

Showing the first eight; more decompositions exist.
