Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103520, here are decompositions:

37 + 103483 = 103520
97 + 103423 = 103520
127 + 103393 = 103520
163 + 103357 = 103520
229 + 103291 = 103520
283 + 103237 = 103520
337 + 103183 = 103520
349 + 103171 = 103520

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 103,520 and was likely granted around 1870.

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