Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8782, here are decompositions:
- 3 + 8779 = 8782
- 29 + 8753 = 8782
- 41 + 8741 = 8782
- 83 + 8699 = 8782
- 89 + 8693 = 8782
- 101 + 8681 = 8782
- 113 + 8669 = 8782
- 173 + 8609 = 8782
Showing the first eight; more decompositions exist.
