Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27874, here are decompositions:
- 23 + 27851 = 27874
- 47 + 27827 = 27874
- 71 + 27803 = 27874
- 83 + 27791 = 27874
- 101 + 27773 = 27874
- 107 + 27767 = 27874
- 131 + 27743 = 27874
- 137 + 27737 = 27874
Showing the first eight; more decompositions exist.
