Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130038, here are decompositions:

11 + 130027 = 130038
17 + 130021 = 130038
67 + 129971 = 130038
71 + 129967 = 130038
79 + 129959 = 130038
101 + 129937 = 130038
137 + 129901 = 130038
151 + 129887 = 130038

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 130,038 and was likely granted around 1872.

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