Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15158, here are decompositions:
- 19 + 15139 = 15158
- 37 + 15121 = 15158
- 67 + 15091 = 15158
- 97 + 15061 = 15158
- 127 + 15031 = 15158
- 211 + 14947 = 15158
- 229 + 14929 = 15158
- 271 + 14887 = 15158
Showing the first eight; more decompositions exist.
