Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130026, here are decompositions:

5 + 130021 = 130026
23 + 130003 = 130026
59 + 129967 = 130026
67 + 129959 = 130026
73 + 129953 = 130026
89 + 129937 = 130026
107 + 129919 = 130026
109 + 129917 = 130026

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 130,026 and was likely granted around 1872.

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