Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28168, here are decompositions:

5 + 28163 = 28168
17 + 28151 = 28168
59 + 28109 = 28168
71 + 28097 = 28168
137 + 28031 = 28168
149 + 28019 = 28168
167 + 28001 = 28168
227 + 27941 = 28168

Showing the first eight; more decompositions exist.
