Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133112, here are decompositions:
- 3 + 133109 = 133112
- 43 + 133069 = 133112
- 61 + 133051 = 133112
- 73 + 133039 = 133112
- 79 + 133033 = 133112
- 151 + 132961 = 133112
- 163 + 132949 = 133112
- 349 + 132763 = 133112
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 133,112 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
