Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43918, here are decompositions:
- 5 + 43913 = 43918
- 29 + 43889 = 43918
- 131 + 43787 = 43918
- 137 + 43781 = 43918
- 197 + 43721 = 43918
- 227 + 43691 = 43918
- 257 + 43661 = 43918
- 269 + 43649 = 43918
Showing the first eight; more decompositions exist.
