Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11320, here are decompositions:

3 + 11317 = 11320
41 + 11279 = 11320
47 + 11273 = 11320
59 + 11261 = 11320
107 + 11213 = 11320
149 + 11171 = 11320
227 + 11093 = 11320
233 + 11087 = 11320

Showing the first eight; more decompositions exist.
