Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6168, here are decompositions:
- 5 + 6163 = 6168
- 17 + 6151 = 6168
- 37 + 6131 = 6168
- 47 + 6121 = 6168
- 67 + 6101 = 6168
- 79 + 6089 = 6168
- 89 + 6079 = 6168
- 101 + 6067 = 6168
Showing the first eight; more decompositions exist.
