Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7976, here are decompositions:
- 13 + 7963 = 7976
- 43 + 7933 = 7976
- 97 + 7879 = 7976
- 103 + 7873 = 7976
- 109 + 7867 = 7976
- 223 + 7753 = 7976
- 277 + 7699 = 7976
- 307 + 7669 = 7976
Showing the first eight; more decompositions exist.
