Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13380, here are decompositions:

13 + 13367 = 13380
41 + 13339 = 13380
43 + 13337 = 13380
53 + 13327 = 13380
67 + 13313 = 13380
71 + 13309 = 13380
83 + 13297 = 13380
89 + 13291 = 13380

Showing the first eight; more decompositions exist.
