Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16826, here are decompositions:
- 3 + 16823 = 16826
- 67 + 16759 = 16826
- 79 + 16747 = 16826
- 97 + 16729 = 16826
- 127 + 16699 = 16826
- 193 + 16633 = 16826
- 223 + 16603 = 16826
- 307 + 16519 = 16826
Showing the first eight; more decompositions exist.
