Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105778, here are decompositions:
- 11 + 105767 = 105778
- 17 + 105761 = 105778
- 251 + 105527 = 105778
- 269 + 105509 = 105778
- 311 + 105467 = 105778
- 389 + 105389 = 105778
- 419 + 105359 = 105778
- 509 + 105269 = 105778
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 105.778 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
