Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2762, here are decompositions:
- 13 + 2749 = 2762
- 31 + 2731 = 2762
- 43 + 2719 = 2762
- 73 + 2689 = 2762
- 79 + 2683 = 2762
- 103 + 2659 = 2762
- 211 + 2551 = 2762
- 223 + 2539 = 2762
Showing the first eight; more decompositions exist.
