Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85864, here are decompositions:
- 11 + 85853 = 85864
- 17 + 85847 = 85864
- 47 + 85817 = 85864
- 71 + 85793 = 85864
- 83 + 85781 = 85864
- 113 + 85751 = 85864
- 131 + 85733 = 85864
- 173 + 85691 = 85864
Showing the first eight; more decompositions exist.
