Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164900, here are decompositions:

7 + 164893 = 164900
19 + 164881 = 164900
61 + 164839 = 164900
79 + 164821 = 164900
157 + 164743 = 164900
193 + 164707 = 164900
199 + 164701 = 164900
223 + 164677 = 164900

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 164,900 and was likely granted around 1874.

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