Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43900, here are decompositions:
- 11 + 43889 = 43900
- 47 + 43853 = 43900
- 107 + 43793 = 43900
- 113 + 43787 = 43900
- 179 + 43721 = 43900
- 239 + 43661 = 43900
- 251 + 43649 = 43900
- 293 + 43607 = 43900
Showing the first eight; more decompositions exist.
