Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43678, here are decompositions:
- 17 + 43661 = 43678
- 29 + 43649 = 43678
- 71 + 43607 = 43678
- 101 + 43577 = 43678
- 137 + 43541 = 43678
- 179 + 43499 = 43678
- 191 + 43487 = 43678
- 197 + 43481 = 43678
Showing the first eight; more decompositions exist.
