Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100124, here are decompositions:
- 67 + 100057 = 100124
- 163 + 99961 = 100124
- 223 + 99901 = 100124
- 307 + 99817 = 100124
- 331 + 99793 = 100124
- 337 + 99787 = 100124
- 457 + 99667 = 100124
- 463 + 99661 = 100124
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 100,124 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
