Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13390, here are decompositions:

23 + 13367 = 13390
53 + 13337 = 13390
59 + 13331 = 13390
131 + 13259 = 13390
149 + 13241 = 13390
173 + 13217 = 13390
227 + 13163 = 13390
239 + 13151 = 13390

Showing the first eight; more decompositions exist.
