Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17992, here are decompositions:
- 3 + 17989 = 17992
- 5 + 17987 = 17992
- 11 + 17981 = 17992
- 53 + 17939 = 17992
- 71 + 17921 = 17992
- 83 + 17909 = 17992
- 89 + 17903 = 17992
- 101 + 17891 = 17992
Showing the first eight; more decompositions exist.
