Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16008, here are decompositions:
- 7 + 16001 = 16008
- 17 + 15991 = 16008
- 37 + 15971 = 16008
- 71 + 15937 = 16008
- 89 + 15919 = 16008
- 101 + 15907 = 16008
- 107 + 15901 = 16008
- 127 + 15881 = 16008
Showing the first eight; more decompositions exist.
