Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85842, here are decompositions:
- 5 + 85837 = 85842
- 11 + 85831 = 85842
- 13 + 85829 = 85842
- 23 + 85819 = 85842
- 61 + 85781 = 85842
- 109 + 85733 = 85842
- 131 + 85711 = 85842
- 139 + 85703 = 85842
Showing the first eight; more decompositions exist.
