Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27858, here are decompositions:
- 7 + 27851 = 27858
- 11 + 27847 = 27858
- 31 + 27827 = 27858
- 41 + 27817 = 27858
- 59 + 27799 = 27858
- 67 + 27791 = 27858
- 79 + 27779 = 27858
- 107 + 27751 = 27858
Showing the first eight; more decompositions exist.
