Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23538, here are decompositions:

7 + 23531 = 23538
29 + 23509 = 23538
41 + 23497 = 23538
79 + 23459 = 23538
107 + 23431 = 23538
139 + 23399 = 23538
167 + 23371 = 23538
181 + 23357 = 23538

Showing the first eight; more decompositions exist.
