Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105864, here are decompositions:
- 47 + 105817 = 105864
- 97 + 105767 = 105864
- 103 + 105761 = 105864
- 113 + 105751 = 105864
- 131 + 105733 = 105864
- 137 + 105727 = 105864
- 163 + 105701 = 105864
- 173 + 105691 = 105864
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105,864 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
