Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15958, here are decompositions:
- 71 + 15887 = 15958
- 149 + 15809 = 15958
- 167 + 15791 = 15958
- 191 + 15767 = 15958
- 197 + 15761 = 15958
- 227 + 15731 = 15958
- 311 + 15647 = 15958
- 317 + 15641 = 15958
Showing the first eight; more decompositions exist.
