Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15164, here are decompositions:
- 3 + 15161 = 15164
- 43 + 15121 = 15164
- 73 + 15091 = 15164
- 103 + 15061 = 15164
- 151 + 15013 = 15164
- 181 + 14983 = 15164
- 241 + 14923 = 15164
- 277 + 14887 = 15164
Showing the first eight; more decompositions exist.
