Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105216, here are decompositions:
- 5 + 105211 = 105216
- 17 + 105199 = 105216
- 43 + 105173 = 105216
- 73 + 105143 = 105216
- 79 + 105137 = 105216
- 109 + 105107 = 105216
- 179 + 105037 = 105216
- 193 + 105023 = 105216
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 105.216 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
