Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133172, here are decompositions:
- 3 + 133169 = 133172
- 19 + 133153 = 133172
- 103 + 133069 = 133172
- 139 + 133033 = 133172
- 211 + 132961 = 133172
- 223 + 132949 = 133172
- 313 + 132859 = 133172
- 409 + 132763 = 133172
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 133,172 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
