Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16984, here are decompositions:
- 3 + 16981 = 16984
- 5 + 16979 = 16984
- 41 + 16943 = 16984
- 47 + 16937 = 16984
- 53 + 16931 = 16984
- 83 + 16901 = 16984
- 101 + 16883 = 16984
- 113 + 16871 = 16984
Showing the first eight; more decompositions exist.
