Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103678, here are decompositions:
- 59 + 103619 = 103678
- 101 + 103577 = 103678
- 149 + 103529 = 103678
- 167 + 103511 = 103678
- 227 + 103451 = 103678
- 257 + 103421 = 103678
- 269 + 103409 = 103678
- 359 + 103319 = 103678
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 103,678 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
