Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13368, here are decompositions:

29 + 13339 = 13368
31 + 13337 = 13368
37 + 13331 = 13368
41 + 13327 = 13368
59 + 13309 = 13368
71 + 13297 = 13368
101 + 13267 = 13368
109 + 13259 = 13368

Showing the first eight; more decompositions exist.
