Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135140, here are decompositions:
- 97 + 135043 = 135140
- 151 + 134989 = 135140
- 193 + 134947 = 135140
- 223 + 134917 = 135140
- 283 + 134857 = 135140
- 409 + 134731 = 135140
- 433 + 134707 = 135140
- 457 + 134683 = 135140
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 135,140 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
