Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16626, here are decompositions:
- 7 + 16619 = 16626
- 19 + 16607 = 16626
- 23 + 16603 = 16626
- 53 + 16573 = 16626
- 59 + 16567 = 16626
- 73 + 16553 = 16626
- 79 + 16547 = 16626
- 97 + 16529 = 16626
Showing the first eight; more decompositions exist.
