Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945500, here are decompositions:

19 + 945481 = 945500
37 + 945463 = 945500
43 + 945457 = 945500
103 + 945397 = 945500
109 + 945391 = 945500
151 + 945349 = 945500
211 + 945289 = 945500
349 + 945151 = 945500

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 945,500 and was likely granted around 1909.

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