Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162268, here are decompositions:

5 + 162263 = 162268
11 + 162257 = 162268
17 + 162251 = 162268
47 + 162221 = 162268
59 + 162209 = 162268
149 + 162119 = 162268
251 + 162017 = 162268
257 + 162011 = 162268

Showing the first eight; more decompositions exist.
