Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16944, here are decompositions:
- 7 + 16937 = 16944
- 13 + 16931 = 16944
- 17 + 16927 = 16944
- 23 + 16921 = 16944
- 41 + 16903 = 16944
- 43 + 16901 = 16944
- 61 + 16883 = 16944
- 73 + 16871 = 16944
Showing the first eight; more decompositions exist.
