Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24400, here are decompositions:

29 + 24371 = 24400
41 + 24359 = 24400
71 + 24329 = 24400
83 + 24317 = 24400
149 + 24251 = 24400
197 + 24203 = 24400
263 + 24137 = 24400
293 + 24107 = 24400

Showing the first eight; more decompositions exist.
