Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12798, here are decompositions:
- 7 + 12791 = 12798
- 17 + 12781 = 12798
- 41 + 12757 = 12798
- 59 + 12739 = 12798
- 101 + 12697 = 12798
- 109 + 12689 = 12798
- 127 + 12671 = 12798
- 139 + 12659 = 12798
Showing the first eight; more decompositions exist.
