Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7922, here are decompositions:
- 3 + 7919 = 7922
- 43 + 7879 = 7922
- 163 + 7759 = 7922
- 181 + 7741 = 7922
- 199 + 7723 = 7922
- 223 + 7699 = 7922
- 241 + 7681 = 7922
- 283 + 7639 = 7922
Showing the first eight; more decompositions exist.
