Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9742, here are decompositions:
- 3 + 9739 = 9742
- 23 + 9719 = 9742
- 53 + 9689 = 9742
- 113 + 9629 = 9742
- 191 + 9551 = 9742
- 251 + 9491 = 9742
- 263 + 9479 = 9742
- 269 + 9473 = 9742
Showing the first eight; more decompositions exist.
