Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13426, here are decompositions:

5 + 13421 = 13426
29 + 13397 = 13426
59 + 13367 = 13426
89 + 13337 = 13426
113 + 13313 = 13426
167 + 13259 = 13426
197 + 13229 = 13426
239 + 13187 = 13426

Showing the first eight; more decompositions exist.
