Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11400, here are decompositions:

7 + 11393 = 11400
17 + 11383 = 11400
31 + 11369 = 11400
47 + 11353 = 11400
71 + 11329 = 11400
79 + 11321 = 11400
83 + 11317 = 11400
89 + 11311 = 11400

Showing the first eight; more decompositions exist.
