Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9858, here are decompositions:
- 7 + 9851 = 9858
- 19 + 9839 = 9858
- 29 + 9829 = 9858
- 41 + 9817 = 9858
- 47 + 9811 = 9858
- 67 + 9791 = 9858
- 71 + 9787 = 9858
- 89 + 9769 = 9858
Showing the first eight; more decompositions exist.
