Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159400, here are decompositions:

11 + 159389 = 159400
53 + 159347 = 159400
89 + 159311 = 159400
107 + 159293 = 159400
113 + 159287 = 159400
167 + 159233 = 159400
173 + 159227 = 159400
191 + 159209 = 159400

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 159,400 and was likely granted around 1873.

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