Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43986, here are decompositions:
- 13 + 43973 = 43986
- 17 + 43969 = 43986
- 23 + 43963 = 43986
- 43 + 43943 = 43986
- 53 + 43933 = 43986
- 73 + 43913 = 43986
- 97 + 43889 = 43986
- 193 + 43793 = 43986
Showing the first eight; more decompositions exist.
