Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177120, here are decompositions:
- 7 + 177113 = 177120
- 11 + 177109 = 177120
- 19 + 177101 = 177120
- 29 + 177091 = 177120
- 101 + 177019 = 177120
- 107 + 177013 = 177120
- 109 + 177011 = 177120
- 113 + 177007 = 177120
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 177,120 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
