Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27838, here are decompositions:
- 11 + 27827 = 27838
- 29 + 27809 = 27838
- 47 + 27791 = 27838
- 59 + 27779 = 27838
- 71 + 27767 = 27838
- 89 + 27749 = 27838
- 101 + 27737 = 27838
- 137 + 27701 = 27838
Showing the first eight; more decompositions exist.
