Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11944, here are decompositions:
- 3 + 11941 = 11944
- 5 + 11939 = 11944
- 11 + 11933 = 11944
- 17 + 11927 = 11944
- 41 + 11903 = 11944
- 47 + 11897 = 11944
- 113 + 11831 = 11944
- 131 + 11813 = 11944
Showing the first eight; more decompositions exist.
