Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11540, here are decompositions:
- 13 + 11527 = 11540
- 37 + 11503 = 11540
- 43 + 11497 = 11540
- 73 + 11467 = 11540
- 97 + 11443 = 11540
- 103 + 11437 = 11540
- 157 + 11383 = 11540
- 211 + 11329 = 11540
Showing the first eight; more decompositions exist.
