Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27864, here are decompositions:
- 13 + 27851 = 27864
- 17 + 27847 = 27864
- 37 + 27827 = 27864
- 41 + 27823 = 27864
- 47 + 27817 = 27864
- 61 + 27803 = 27864
- 71 + 27793 = 27864
- 73 + 27791 = 27864
Showing the first eight; more decompositions exist.
