Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130420, here are decompositions:

11 + 130409 = 130420
41 + 130379 = 130420
53 + 130367 = 130420
71 + 130349 = 130420
83 + 130337 = 130420
113 + 130307 = 130420
167 + 130253 = 130420
179 + 130241 = 130420

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 130,420 and was likely granted around 1872.

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