Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7982, here are decompositions:
- 19 + 7963 = 7982
- 31 + 7951 = 7982
- 103 + 7879 = 7982
- 109 + 7873 = 7982
- 193 + 7789 = 7982
- 223 + 7759 = 7982
- 229 + 7753 = 7982
- 241 + 7741 = 7982
Showing the first eight; more decompositions exist.
