Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12844, here are decompositions:
- 3 + 12841 = 12844
- 23 + 12821 = 12844
- 53 + 12791 = 12844
- 101 + 12743 = 12844
- 131 + 12713 = 12844
- 173 + 12671 = 12844
- 191 + 12653 = 12844
- 197 + 12647 = 12844
Showing the first eight; more decompositions exist.
