Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11916, here are decompositions:
- 7 + 11909 = 11916
- 13 + 11903 = 11916
- 19 + 11897 = 11916
- 29 + 11887 = 11916
- 53 + 11863 = 11916
- 83 + 11833 = 11916
- 89 + 11827 = 11916
- 103 + 11813 = 11916
Showing the first eight; more decompositions exist.
