Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43958, here are decompositions:
- 7 + 43951 = 43958
- 67 + 43891 = 43958
- 157 + 43801 = 43958
- 181 + 43777 = 43958
- 199 + 43759 = 43958
- 241 + 43717 = 43958
- 307 + 43651 = 43958
- 331 + 43627 = 43958
Showing the first eight; more decompositions exist.
