Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12968, here are decompositions:
- 61 + 12907 = 12968
- 79 + 12889 = 12968
- 127 + 12841 = 12968
- 139 + 12829 = 12968
- 211 + 12757 = 12968
- 229 + 12739 = 12968
- 271 + 12697 = 12968
- 331 + 12637 = 12968
Showing the first eight; more decompositions exist.
