Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100512, here are decompositions:
- 11 + 100501 = 100512
- 19 + 100493 = 100512
- 29 + 100483 = 100512
- 43 + 100469 = 100512
- 53 + 100459 = 100512
- 101 + 100411 = 100512
- 109 + 100403 = 100512
- 149 + 100363 = 100512
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 100,512 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
