Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43858, here are decompositions:
- 5 + 43853 = 43858
- 71 + 43787 = 43858
- 137 + 43721 = 43858
- 167 + 43691 = 43858
- 197 + 43661 = 43858
- 251 + 43607 = 43858
- 281 + 43577 = 43858
- 317 + 43541 = 43858
Showing the first eight; more decompositions exist.
