Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164644, here are decompositions:

17 + 164627 = 164644
23 + 164621 = 164644
113 + 164531 = 164644
131 + 164513 = 164644
167 + 164477 = 164644
173 + 164471 = 164644
197 + 164447 = 164644
257 + 164387 = 164644

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 164,644 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
