Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16570, here are decompositions:
- 3 + 16567 = 16570
- 17 + 16553 = 16570
- 23 + 16547 = 16570
- 41 + 16529 = 16570
- 83 + 16487 = 16570
- 89 + 16481 = 16570
- 137 + 16433 = 16570
- 149 + 16421 = 16570
Showing the first eight; more decompositions exist.
