Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15916, here are decompositions:
- 3 + 15913 = 15916
- 29 + 15887 = 15916
- 107 + 15809 = 15916
- 113 + 15803 = 15916
- 149 + 15767 = 15916
- 167 + 15749 = 15916
- 179 + 15737 = 15916
- 233 + 15683 = 15916
Showing the first eight; more decompositions exist.
