Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2712, here are decompositions:
- 5 + 2707 = 2712
- 13 + 2699 = 2712
- 19 + 2693 = 2712
- 23 + 2689 = 2712
- 29 + 2683 = 2712
- 41 + 2671 = 2712
- 53 + 2659 = 2712
- 79 + 2633 = 2712
Showing the first eight; more decompositions exist.
