Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27804, here are decompositions:
- 5 + 27799 = 27804
- 11 + 27793 = 27804
- 13 + 27791 = 27804
- 31 + 27773 = 27804
- 37 + 27767 = 27804
- 41 + 27763 = 27804
- 53 + 27751 = 27804
- 61 + 27743 = 27804
Showing the first eight; more decompositions exist.
