Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 134720, here are decompositions:

13 + 134707 = 134720
37 + 134683 = 134720
43 + 134677 = 134720
127 + 134593 = 134720
139 + 134581 = 134720
277 + 134443 = 134720
283 + 134437 = 134720
349 + 134371 = 134720

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 134,720 and was likely granted around 1872.

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