Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130112, here are decompositions:
- 13 + 130099 = 130112
- 43 + 130069 = 130112
- 61 + 130051 = 130112
- 109 + 130003 = 130112
- 193 + 129919 = 130112
- 211 + 129901 = 130112
- 271 + 129841 = 130112
- 349 + 129763 = 130112
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 130,112 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
