Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23540, here are decompositions:

3 + 23537 = 23540
31 + 23509 = 23540
43 + 23497 = 23540
67 + 23473 = 23540
109 + 23431 = 23540
229 + 23311 = 23540
271 + 23269 = 23540
313 + 23227 = 23540

Showing the first eight; more decompositions exist.
