Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13966, here are decompositions:
- 3 + 13963 = 13966
- 53 + 13913 = 13966
- 59 + 13907 = 13966
- 83 + 13883 = 13966
- 89 + 13877 = 13966
- 107 + 13859 = 13966
- 137 + 13829 = 13966
- 167 + 13799 = 13966
Showing the first eight; more decompositions exist.
