Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43942, here are decompositions:
- 29 + 43913 = 43942
- 53 + 43889 = 43942
- 89 + 43853 = 43942
- 149 + 43793 = 43942
- 251 + 43691 = 43942
- 281 + 43661 = 43942
- 293 + 43649 = 43942
- 401 + 43541 = 43942
Showing the first eight; more decompositions exist.
