Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7994, here are decompositions:
- 31 + 7963 = 7994
- 43 + 7951 = 7994
- 61 + 7933 = 7994
- 67 + 7927 = 7994
- 127 + 7867 = 7994
- 241 + 7753 = 7994
- 271 + 7723 = 7994
- 277 + 7717 = 7994
Showing the first eight; more decompositions exist.
