Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15994, here are decompositions:
- 3 + 15991 = 15994
- 23 + 15971 = 15994
- 71 + 15923 = 15994
- 107 + 15887 = 15994
- 113 + 15881 = 15994
- 191 + 15803 = 15994
- 197 + 15797 = 15994
- 227 + 15767 = 15994
Showing the first eight; more decompositions exist.
