Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85900, here are decompositions:
- 11 + 85889 = 85900
- 47 + 85853 = 85900
- 53 + 85847 = 85900
- 71 + 85829 = 85900
- 83 + 85817 = 85900
- 107 + 85793 = 85900
- 149 + 85751 = 85900
- 167 + 85733 = 85900
Showing the first eight; more decompositions exist.
