Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15970, here are decompositions:
- 11 + 15959 = 15970
- 47 + 15923 = 15970
- 83 + 15887 = 15970
- 89 + 15881 = 15970
- 167 + 15803 = 15970
- 173 + 15797 = 15970
- 179 + 15791 = 15970
- 197 + 15773 = 15970
Showing the first eight; more decompositions exist.
