Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12340, here are decompositions:

11 + 12329 = 12340
17 + 12323 = 12340
59 + 12281 = 12340
71 + 12269 = 12340
89 + 12251 = 12340
101 + 12239 = 12340
113 + 12227 = 12340
137 + 12203 = 12340

Showing the first eight; more decompositions exist.
