Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16620, here are decompositions:
- 13 + 16607 = 16620
- 17 + 16603 = 16620
- 47 + 16573 = 16620
- 53 + 16567 = 16620
- 59 + 16561 = 16620
- 67 + 16553 = 16620
- 73 + 16547 = 16620
- 101 + 16519 = 16620
Showing the first eight; more decompositions exist.
