Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13540, here are decompositions:
- 3 + 13537 = 13540
- 17 + 13523 = 13540
- 41 + 13499 = 13540
- 53 + 13487 = 13540
- 71 + 13469 = 13540
- 83 + 13457 = 13540
- 89 + 13451 = 13540
- 173 + 13367 = 13540
Showing the first eight; more decompositions exist.
