Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100678, here are decompositions:
- 5 + 100673 = 100678
- 29 + 100649 = 100678
- 131 + 100547 = 100678
- 167 + 100511 = 100678
- 317 + 100361 = 100678
- 509 + 100169 = 100678
- 569 + 100109 = 100678
- 659 + 100019 = 100678
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 100,678 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
