Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120172, here are decompositions:
- 5 + 120167 = 120172
- 131 + 120041 = 120172
- 179 + 119993 = 120172
- 191 + 119981 = 120172
- 251 + 119921 = 120172
- 281 + 119891 = 120172
- 359 + 119813 = 120172
- 389 + 119783 = 120172
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 120,172 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
