Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43978, here are decompositions:
- 5 + 43973 = 43978
- 17 + 43961 = 43978
- 89 + 43889 = 43978
- 191 + 43787 = 43978
- 197 + 43781 = 43978
- 257 + 43721 = 43978
- 317 + 43661 = 43978
- 401 + 43577 = 43978
Showing the first eight; more decompositions exist.
