Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9558, here are decompositions:
- 7 + 9551 = 9558
- 11 + 9547 = 9558
- 19 + 9539 = 9558
- 37 + 9521 = 9558
- 47 + 9511 = 9558
- 61 + 9497 = 9558
- 67 + 9491 = 9558
- 79 + 9479 = 9558
Showing the first eight; more decompositions exist.
