Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9828, here are decompositions:
- 11 + 9817 = 9828
- 17 + 9811 = 9828
- 37 + 9791 = 9828
- 41 + 9787 = 9828
- 47 + 9781 = 9828
- 59 + 9769 = 9828
- 61 + 9767 = 9828
- 79 + 9749 = 9828
Showing the first eight; more decompositions exist.
