Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43972, here are decompositions:
- 3 + 43969 = 43972
- 11 + 43961 = 43972
- 29 + 43943 = 43972
- 59 + 43913 = 43972
- 83 + 43889 = 43972
- 179 + 43793 = 43972
- 191 + 43781 = 43972
- 251 + 43721 = 43972
Showing the first eight; more decompositions exist.
