Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130270, here are decompositions:

3 + 130267 = 130270
11 + 130259 = 130270
17 + 130253 = 130270
29 + 130241 = 130270
47 + 130223 = 130270
59 + 130211 = 130270
71 + 130199 = 130270
149 + 130121 = 130270

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 130,270 and was likely granted around 1872.

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