Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100148, here are decompositions:
- 19 + 100129 = 100148
- 79 + 100069 = 100148
- 157 + 99991 = 100148
- 241 + 99907 = 100148
- 271 + 99877 = 100148
- 277 + 99871 = 100148
- 331 + 99817 = 100148
- 439 + 99709 = 100148
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 100,148 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
