Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2756, here are decompositions:
- 3 + 2753 = 2756
- 7 + 2749 = 2756
- 37 + 2719 = 2756
- 43 + 2713 = 2756
- 67 + 2689 = 2756
- 73 + 2683 = 2756
- 79 + 2677 = 2756
- 97 + 2659 = 2756
Showing the first eight; more decompositions exist.
