Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13968, here are decompositions:
- 5 + 13963 = 13968
- 37 + 13931 = 13968
- 47 + 13921 = 13968
- 61 + 13907 = 13968
- 67 + 13901 = 13968
- 89 + 13879 = 13968
- 109 + 13859 = 13968
- 127 + 13841 = 13968
Showing the first eight; more decompositions exist.
