Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2708, here are decompositions:
- 19 + 2689 = 2708
- 31 + 2677 = 2708
- 37 + 2671 = 2708
- 61 + 2647 = 2708
- 151 + 2557 = 2708
- 157 + 2551 = 2708
- 241 + 2467 = 2708
- 271 + 2437 = 2708
Showing the first eight; more decompositions exist.
