Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164656, here are decompositions:
- 3 + 164653 = 164656
- 29 + 164627 = 164656
- 179 + 164477 = 164656
- 227 + 164429 = 164656
- 269 + 164387 = 164656
- 293 + 164363 = 164656
- 347 + 164309 = 164656
- 389 + 164267 = 164656
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 164,656 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
