Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16000, here are decompositions:
- 29 + 15971 = 16000
- 41 + 15959 = 16000
- 113 + 15887 = 16000
- 191 + 15809 = 16000
- 197 + 15803 = 16000
- 227 + 15773 = 16000
- 233 + 15767 = 16000
- 239 + 15761 = 16000
Showing the first eight; more decompositions exist.
