Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165008, here are decompositions:

7 + 165001 = 165008
97 + 164911 = 165008
127 + 164881 = 165008
199 + 164809 = 165008
241 + 164767 = 165008
307 + 164701 = 165008
331 + 164677 = 165008
409 + 164599 = 165008

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 165,008 and was likely granted around 1874.

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