Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11328, here are decompositions:

7 + 11321 = 11328
11 + 11317 = 11328
17 + 11311 = 11328
29 + 11299 = 11328
41 + 11287 = 11328
67 + 11261 = 11328
71 + 11257 = 11328
89 + 11239 = 11328

Showing the first eight; more decompositions exist.
