Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13420, here are decompositions:

3 + 13417 = 13420
23 + 13397 = 13420
53 + 13367 = 13420
83 + 13337 = 13420
89 + 13331 = 13420
107 + 13313 = 13420
179 + 13241 = 13420
191 + 13229 = 13420

Showing the first eight; more decompositions exist.
