Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105124, here are decompositions:
- 17 + 105107 = 105124
- 53 + 105071 = 105124
- 101 + 105023 = 105124
- 137 + 104987 = 105124
- 191 + 104933 = 105124
- 233 + 104891 = 105124
- 293 + 104831 = 105124
- 401 + 104723 = 105124
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 105.124 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
