Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23398, here are decompositions:

29 + 23369 = 23398
41 + 23357 = 23398
59 + 23339 = 23398
71 + 23327 = 23398
101 + 23297 = 23398
107 + 23291 = 23398
197 + 23201 = 23398
239 + 23159 = 23398

Showing the first eight; more decompositions exist.
