Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85824, here are decompositions:
- 5 + 85819 = 85824
- 7 + 85817 = 85824
- 31 + 85793 = 85824
- 43 + 85781 = 85824
- 73 + 85751 = 85824
- 107 + 85717 = 85824
- 113 + 85711 = 85824
- 157 + 85667 = 85824
Showing the first eight; more decompositions exist.
