Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11268, here are decompositions:

7 + 11261 = 11268
11 + 11257 = 11268
17 + 11251 = 11268
29 + 11239 = 11268
71 + 11197 = 11268
97 + 11171 = 11268
107 + 11161 = 11268
109 + 11159 = 11268

Showing the first eight; more decompositions exist.
