Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2748, here are decompositions:
- 7 + 2741 = 2748
- 17 + 2731 = 2748
- 19 + 2729 = 2748
- 29 + 2719 = 2748
- 37 + 2711 = 2748
- 41 + 2707 = 2748
- 59 + 2689 = 2748
- 61 + 2687 = 2748
Showing the first eight; more decompositions exist.
