Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130520, here are decompositions:

3 + 130517 = 130520
7 + 130513 = 130520
31 + 130489 = 130520
37 + 130483 = 130520
43 + 130477 = 130520
73 + 130447 = 130520
97 + 130423 = 130520
109 + 130411 = 130520

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 130,520 and was likely granted around 1872.

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