Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168028, here are decompositions:

5 + 168023 = 168028
41 + 167987 = 168028
137 + 167891 = 168028
149 + 167879 = 168028
167 + 167861 = 168028
227 + 167801 = 168028
251 + 167777 = 168028
257 + 167771 = 168028

Showing the first eight; more decompositions exist.
