Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13392, here are decompositions:

11 + 13381 = 13392
53 + 13339 = 13392
61 + 13331 = 13392
79 + 13313 = 13392
83 + 13309 = 13392
101 + 13291 = 13392
151 + 13241 = 13392
163 + 13229 = 13392

Showing the first eight; more decompositions exist.
