Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115724, here are decompositions:
- 31 + 115693 = 115724
- 61 + 115663 = 115724
- 67 + 115657 = 115724
- 127 + 115597 = 115724
- 163 + 115561 = 115724
- 211 + 115513 = 115724
- 397 + 115327 = 115724
- 421 + 115303 = 115724
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 115,724 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
