Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131944, here are decompositions:
- 3 + 131941 = 131944
- 5 + 131939 = 131944
- 11 + 131933 = 131944
- 17 + 131927 = 131944
- 53 + 131891 = 131944
- 83 + 131861 = 131944
- 107 + 131837 = 131944
- 167 + 131777 = 131944
Showing the first eight; more decompositions exist.
