Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125340, here are decompositions:
- 11 + 125329 = 125340
- 29 + 125311 = 125340
- 37 + 125303 = 125340
- 41 + 125299 = 125340
- 53 + 125287 = 125340
- 71 + 125269 = 125340
- 79 + 125261 = 125340
- 97 + 125243 = 125340
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 125,340 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
