Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23388, here are decompositions:

17 + 23371 = 23388
19 + 23369 = 23388
31 + 23357 = 23388
61 + 23327 = 23388
67 + 23321 = 23388
97 + 23291 = 23388
109 + 23279 = 23388
137 + 23251 = 23388

Showing the first eight; more decompositions exist.
