Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2684, here are decompositions:
- 7 + 2677 = 2684
- 13 + 2671 = 2684
- 37 + 2647 = 2684
- 67 + 2617 = 2684
- 127 + 2557 = 2684
- 163 + 2521 = 2684
- 181 + 2503 = 2684
- 211 + 2473 = 2684
Showing the first eight; more decompositions exist.
