Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130100, here are decompositions:

13 + 130087 = 130100
31 + 130069 = 130100
43 + 130057 = 130100
73 + 130027 = 130100
79 + 130021 = 130100
97 + 130003 = 130100
163 + 129937 = 130100
181 + 129919 = 130100

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 130,100 and was likely granted around 1872.

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