Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87894, here are decompositions:
- 7 + 87887 = 87894
- 13 + 87881 = 87894
- 17 + 87877 = 87894
- 41 + 87853 = 87894
- 61 + 87833 = 87894
- 83 + 87811 = 87894
- 97 + 87797 = 87894
- 101 + 87793 = 87894
Showing the first eight; more decompositions exist.
