Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16018, here are decompositions:
- 11 + 16007 = 16018
- 17 + 16001 = 16018
- 47 + 15971 = 16018
- 59 + 15959 = 16018
- 131 + 15887 = 16018
- 137 + 15881 = 16018
- 227 + 15791 = 16018
- 251 + 15767 = 16018
Showing the first eight; more decompositions exist.
