Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159210, here are decompositions:

11 + 159199 = 159210
17 + 159193 = 159210
19 + 159191 = 159210
31 + 159179 = 159210
41 + 159169 = 159210
43 + 159167 = 159210
53 + 159157 = 159210
97 + 159113 = 159210

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 159,210 and was likely granted around 1873.

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