Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12944, here are decompositions:
- 3 + 12941 = 12944
- 37 + 12907 = 12944
- 103 + 12841 = 12944
- 163 + 12781 = 12944
- 181 + 12763 = 12944
- 223 + 12721 = 12944
- 241 + 12703 = 12944
- 307 + 12637 = 12944
Showing the first eight; more decompositions exist.
