Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23240, here are decompositions:

13 + 23227 = 23240
31 + 23209 = 23240
37 + 23203 = 23240
43 + 23197 = 23240
67 + 23173 = 23240
73 + 23167 = 23240
97 + 23143 = 23240
109 + 23131 = 23240

Showing the first eight; more decompositions exist.
