Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13944, here are decompositions:
- 11 + 13933 = 13944
- 13 + 13931 = 13944
- 23 + 13921 = 13944
- 31 + 13913 = 13944
- 37 + 13907 = 13944
- 41 + 13903 = 13944
- 43 + 13901 = 13944
- 61 + 13883 = 13944
Showing the first eight; more decompositions exist.
