Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115940, here are decompositions:
- 7 + 115933 = 115940
- 37 + 115903 = 115940
- 61 + 115879 = 115940
- 67 + 115873 = 115940
- 79 + 115861 = 115940
- 103 + 115837 = 115940
- 109 + 115831 = 115940
- 157 + 115783 = 115940
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 115,940 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
