Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43982, here are decompositions:
- 13 + 43969 = 43982
- 19 + 43963 = 43982
- 31 + 43951 = 43982
- 181 + 43801 = 43982
- 193 + 43789 = 43982
- 199 + 43783 = 43982
- 223 + 43759 = 43982
- 229 + 43753 = 43982
Showing the first eight; more decompositions exist.
