Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28234, here are decompositions:

5 + 28229 = 28234
23 + 28211 = 28234
53 + 28181 = 28234
71 + 28163 = 28234
83 + 28151 = 28234
137 + 28097 = 28234
233 + 28001 = 28234
251 + 27983 = 28234

Showing the first eight; more decompositions exist.
