Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12916, here are decompositions:
- 5 + 12911 = 12916
- 17 + 12899 = 12916
- 23 + 12893 = 12916
- 107 + 12809 = 12916
- 173 + 12743 = 12916
- 227 + 12689 = 12916
- 257 + 12659 = 12916
- 263 + 12653 = 12916
Showing the first eight; more decompositions exist.
