Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105278, here are decompositions:
- 67 + 105211 = 105278
- 79 + 105199 = 105278
- 181 + 105097 = 105278
- 241 + 105037 = 105278
- 307 + 104971 = 105278
- 331 + 104947 = 105278
- 367 + 104911 = 105278
- 409 + 104869 = 105278
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 105.278 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
