Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100140, here are decompositions:
- 11 + 100129 = 100140
- 31 + 100109 = 100140
- 37 + 100103 = 100140
- 71 + 100069 = 100140
- 83 + 100057 = 100140
- 97 + 100043 = 100140
- 137 + 100003 = 100140
- 149 + 99991 = 100140
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 100,140 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
