Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43940, here are decompositions:
- 7 + 43933 = 43940
- 73 + 43867 = 43940
- 139 + 43801 = 43940
- 151 + 43789 = 43940
- 157 + 43783 = 43940
- 163 + 43777 = 43940
- 181 + 43759 = 43940
- 223 + 43717 = 43940
Showing the first eight; more decompositions exist.
