Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6782, here are decompositions:
- 3 + 6779 = 6782
- 19 + 6763 = 6782
- 73 + 6709 = 6782
- 79 + 6703 = 6782
- 103 + 6679 = 6782
- 109 + 6673 = 6782
- 163 + 6619 = 6782
- 211 + 6571 = 6782
Showing the first eight; more decompositions exist.
