Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105512, here are decompositions:
- 3 + 105509 = 105512
- 13 + 105499 = 105512
- 139 + 105373 = 105512
- 151 + 105361 = 105512
- 181 + 105331 = 105512
- 193 + 105319 = 105512
- 283 + 105229 = 105512
- 313 + 105199 = 105512
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 105 512 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
