Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105678, here are decompositions:
- 5 + 105673 = 105678
- 11 + 105667 = 105678
- 29 + 105649 = 105678
- 59 + 105619 = 105678
- 71 + 105607 = 105678
- 137 + 105541 = 105678
- 149 + 105529 = 105678
- 151 + 105527 = 105678
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 105 678 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
