Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15964, here are decompositions:
- 5 + 15959 = 15964
- 41 + 15923 = 15964
- 83 + 15881 = 15964
- 167 + 15797 = 15964
- 173 + 15791 = 15964
- 191 + 15773 = 15964
- 197 + 15767 = 15964
- 227 + 15737 = 15964
Showing the first eight; more decompositions exist.
