Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2722, here are decompositions:
- 3 + 2719 = 2722
- 11 + 2711 = 2722
- 23 + 2699 = 2722
- 29 + 2693 = 2722
- 59 + 2663 = 2722
- 89 + 2633 = 2722
- 101 + 2621 = 2722
- 113 + 2609 = 2722
Showing the first eight; more decompositions exist.
