Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18016, here are decompositions:
- 3 + 18013 = 18016
- 29 + 17987 = 18016
- 59 + 17957 = 18016
- 107 + 17909 = 18016
- 113 + 17903 = 18016
- 179 + 17837 = 18016
- 227 + 17789 = 18016
- 233 + 17783 = 18016
Showing the first eight; more decompositions exist.
