Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43660, here are decompositions:
- 11 + 43649 = 43660
- 47 + 43613 = 43660
- 53 + 43607 = 43660
- 83 + 43577 = 43660
- 173 + 43487 = 43660
- 179 + 43481 = 43660
- 233 + 43427 = 43660
- 257 + 43403 = 43660
Showing the first eight; more decompositions exist.
