Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105268, here are decompositions:

5 + 105263 = 105268
17 + 105251 = 105268
29 + 105239 = 105268
41 + 105227 = 105268
101 + 105167 = 105268
131 + 105137 = 105268
197 + 105071 = 105268
269 + 104999 = 105268

Showing the first eight; more decompositions exist.
