Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2768, here are decompositions:
- 19 + 2749 = 2768
- 37 + 2731 = 2768
- 61 + 2707 = 2768
- 79 + 2689 = 2768
- 97 + 2671 = 2768
- 109 + 2659 = 2768
- 151 + 2617 = 2768
- 211 + 2557 = 2768
Showing the first eight; more decompositions exist.
