Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7934, here are decompositions:
- 7 + 7927 = 7934
- 61 + 7873 = 7934
- 67 + 7867 = 7934
- 181 + 7753 = 7934
- 193 + 7741 = 7934
- 211 + 7723 = 7934
- 313 + 7621 = 7934
- 331 + 7603 = 7934
Showing the first eight; more decompositions exist.
