Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9804, here are decompositions:
- 13 + 9791 = 9804
- 17 + 9787 = 9804
- 23 + 9781 = 9804
- 37 + 9767 = 9804
- 61 + 9743 = 9804
- 71 + 9733 = 9804
- 83 + 9721 = 9804
- 107 + 9697 = 9804
Showing the first eight; more decompositions exist.
