Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13312, here are decompositions:

3 + 13309 = 13312
53 + 13259 = 13312
71 + 13241 = 13312
83 + 13229 = 13312
149 + 13163 = 13312
191 + 13121 = 13312
263 + 13049 = 13312
269 + 13043 = 13312

Showing the first eight; more decompositions exist.
