Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2706, here are decompositions:
- 7 + 2699 = 2706
- 13 + 2693 = 2706
- 17 + 2689 = 2706
- 19 + 2687 = 2706
- 23 + 2683 = 2706
- 29 + 2677 = 2706
- 43 + 2663 = 2706
- 47 + 2659 = 2706
Showing the first eight; more decompositions exist.
