Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23500, here are decompositions:

3 + 23497 = 23500
41 + 23459 = 23500
53 + 23447 = 23500
83 + 23417 = 23500
101 + 23399 = 23500
131 + 23369 = 23500
167 + 23333 = 23500
173 + 23327 = 23500

Showing the first eight; more decompositions exist.
