Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13376, here are decompositions:

37 + 13339 = 13376
67 + 13309 = 13376
79 + 13297 = 13376
109 + 13267 = 13376
127 + 13249 = 13376
157 + 13219 = 13376
193 + 13183 = 13376
199 + 13177 = 13376

Showing the first eight; more decompositions exist.
