Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12804, here are decompositions:
- 5 + 12799 = 12804
- 13 + 12791 = 12804
- 23 + 12781 = 12804
- 41 + 12763 = 12804
- 47 + 12757 = 12804
- 61 + 12743 = 12804
- 83 + 12721 = 12804
- 101 + 12703 = 12804
Showing the first eight; more decompositions exist.
