Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7944, here are decompositions:
- 7 + 7937 = 7944
- 11 + 7933 = 7944
- 17 + 7927 = 7944
- 37 + 7907 = 7944
- 43 + 7901 = 7944
- 61 + 7883 = 7944
- 67 + 7877 = 7944
- 71 + 7873 = 7944
Showing the first eight; more decompositions exist.
