Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23508, here are decompositions:

11 + 23497 = 23508
61 + 23447 = 23508
109 + 23399 = 23508
137 + 23371 = 23508
139 + 23369 = 23508
151 + 23357 = 23508
181 + 23327 = 23508
197 + 23311 = 23508

Showing the first eight; more decompositions exist.
