Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130172, here are decompositions:

73 + 130099 = 130172
103 + 130069 = 130172
151 + 130021 = 130172
271 + 129901 = 130172
331 + 129841 = 130172
379 + 129793 = 130172
409 + 129763 = 130172
439 + 129733 = 130172

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 130,172 and was likely granted around 1872.

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