Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146000, here are decompositions:

13 + 145987 = 146000
31 + 145969 = 146000
37 + 145963 = 146000
67 + 145933 = 146000
97 + 145903 = 146000
103 + 145897 = 146000
139 + 145861 = 146000
181 + 145819 = 146000

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 146,000 and was likely granted around 1873.

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