Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43540, here are decompositions:
- 23 + 43517 = 43540
- 41 + 43499 = 43540
- 53 + 43487 = 43540
- 59 + 43481 = 43540
- 83 + 43457 = 43540
- 89 + 43451 = 43540
- 113 + 43427 = 43540
- 137 + 43403 = 43540
Showing the first eight; more decompositions exist.
