Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16782, here are decompositions:
- 19 + 16763 = 16782
- 23 + 16759 = 16782
- 41 + 16741 = 16782
- 53 + 16729 = 16782
- 79 + 16703 = 16782
- 83 + 16699 = 16782
- 89 + 16693 = 16782
- 109 + 16673 = 16782
Showing the first eight; more decompositions exist.
