Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15170, here are decompositions:
- 31 + 15139 = 15170
- 79 + 15091 = 15170
- 97 + 15073 = 15170
- 109 + 15061 = 15170
- 139 + 15031 = 15170
- 157 + 15013 = 15170
- 223 + 14947 = 15170
- 241 + 14929 = 15170
Showing the first eight; more decompositions exist.
