Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173420, here are decompositions:
- 61 + 173359 = 173420
- 73 + 173347 = 173420
- 127 + 173293 = 173420
- 157 + 173263 = 173420
- 211 + 173209 = 173420
- 229 + 173191 = 173420
- 271 + 173149 = 173420
- 283 + 173137 = 173420
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 173,420 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
