Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15256, here are decompositions:

23 + 15233 = 15256
29 + 15227 = 15256
83 + 15173 = 15256
107 + 15149 = 15256
149 + 15107 = 15256
173 + 15083 = 15256
179 + 15077 = 15256
239 + 15017 = 15256

Showing the first eight; more decompositions exist.
