Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11960, here are decompositions:
- 7 + 11953 = 11960
- 19 + 11941 = 11960
- 37 + 11923 = 11960
- 73 + 11887 = 11960
- 97 + 11863 = 11960
- 127 + 11833 = 11960
- 139 + 11821 = 11960
- 181 + 11779 = 11960
Showing the first eight; more decompositions exist.
