Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133870, here are decompositions:
- 17 + 133853 = 133870
- 59 + 133811 = 133870
- 89 + 133781 = 133870
- 101 + 133769 = 133870
- 137 + 133733 = 133870
- 173 + 133697 = 133870
- 179 + 133691 = 133870
- 197 + 133673 = 133870
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 133,870 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
