Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105254, here are decompositions:
- 3 + 105251 = 105254
- 43 + 105211 = 105254
- 157 + 105097 = 105254
- 223 + 105031 = 105254
- 283 + 104971 = 105254
- 307 + 104947 = 105254
- 337 + 104917 = 105254
- 547 + 104707 = 105254
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 105 254 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
