Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7916, here are decompositions:
- 37 + 7879 = 7916
- 43 + 7873 = 7916
- 127 + 7789 = 7916
- 157 + 7759 = 7916
- 163 + 7753 = 7916
- 193 + 7723 = 7916
- 199 + 7717 = 7916
- 229 + 7687 = 7916
Showing the first eight; more decompositions exist.
