Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101372, here are decompositions:
- 13 + 101359 = 101372
- 31 + 101341 = 101372
- 79 + 101293 = 101372
- 151 + 101221 = 101372
- 163 + 101209 = 101372
- 199 + 101173 = 101372
- 211 + 101161 = 101372
- 223 + 101149 = 101372
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 101,372 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
