Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158160, here are decompositions:

17 + 158143 = 158160
19 + 158141 = 158160
31 + 158129 = 158160
47 + 158113 = 158160
83 + 158077 = 158160
89 + 158071 = 158160
113 + 158047 = 158160
131 + 158029 = 158160

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 158,160 and was likely granted around 1873.

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