Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164850, here are decompositions:

11 + 164839 = 164850
13 + 164837 = 164850
19 + 164831 = 164850
29 + 164821 = 164850
41 + 164809 = 164850
61 + 164789 = 164850
79 + 164771 = 164850
83 + 164767 = 164850

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 164,850 and was likely granted around 1874.

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