Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11216, here are decompositions:

3 + 11213 = 11216
19 + 11197 = 11216
43 + 11173 = 11216
67 + 11149 = 11216
97 + 11119 = 11216
103 + 11113 = 11216
157 + 11059 = 11216
223 + 10993 = 11216

Showing the first eight; more decompositions exist.
