Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105240, here are decompositions:
- 11 + 105229 = 105240
- 13 + 105227 = 105240
- 29 + 105211 = 105240
- 41 + 105199 = 105240
- 67 + 105173 = 105240
- 73 + 105167 = 105240
- 97 + 105143 = 105240
- 103 + 105137 = 105240
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 105.240 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
