Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17928, here are decompositions:
- 5 + 17923 = 17928
- 7 + 17921 = 17928
- 17 + 17911 = 17928
- 19 + 17909 = 17928
- 37 + 17891 = 17928
- 47 + 17881 = 17928
- 89 + 17839 = 17928
- 101 + 17827 = 17928
Showing the first eight; more decompositions exist.
