Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16606, here are decompositions:
- 3 + 16603 = 16606
- 53 + 16553 = 16606
- 59 + 16547 = 16606
- 113 + 16493 = 16606
- 173 + 16433 = 16606
- 179 + 16427 = 16606
- 257 + 16349 = 16606
- 353 + 16253 = 16606
Showing the first eight; more decompositions exist.
