Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130090, here are decompositions:

3 + 130087 = 130090
11 + 130079 = 130090
17 + 130073 = 130090
47 + 130043 = 130090
131 + 129959 = 130090
137 + 129953 = 130090
173 + 129917 = 130090
197 + 129893 = 130090

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 130,090 and was likely granted around 1872.

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