Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29128, here are decompositions:

5 + 29123 = 29128
101 + 29027 = 29128
107 + 29021 = 29128
149 + 28979 = 29128
167 + 28961 = 29128
179 + 28949 = 29128
227 + 28901 = 29128
257 + 28871 = 29128

Showing the first eight; more decompositions exist.
