Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11286, here are decompositions:

7 + 11279 = 11286
13 + 11273 = 11286
29 + 11257 = 11286
43 + 11243 = 11286
47 + 11239 = 11286
73 + 11213 = 11286
89 + 11197 = 11286
109 + 11177 = 11286

Showing the first eight; more decompositions exist.
