Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100172, here are decompositions:
- 3 + 100169 = 100172
- 19 + 100153 = 100172
- 43 + 100129 = 100172
- 103 + 100069 = 100172
- 181 + 99991 = 100172
- 211 + 99961 = 100172
- 271 + 99901 = 100172
- 313 + 99859 = 100172
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 100,172 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
