Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102268, here are decompositions:

17 + 102251 = 102268
71 + 102197 = 102268
107 + 102161 = 102268
167 + 102101 = 102268
191 + 102077 = 102268
197 + 102071 = 102268
269 + 101999 = 102268
281 + 101987 = 102268

Showing the first eight; more decompositions exist.
