Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105768, here are decompositions:
- 7 + 105761 = 105768
- 17 + 105751 = 105768
- 41 + 105727 = 105768
- 67 + 105701 = 105768
- 101 + 105667 = 105768
- 149 + 105619 = 105768
- 167 + 105601 = 105768
- 211 + 105557 = 105768
Showing the first eight; more decompositions exist.
