Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130230, here are decompositions:

7 + 130223 = 130230
19 + 130211 = 130230
29 + 130201 = 130230
31 + 130199 = 130230
47 + 130183 = 130230
59 + 130171 = 130230
83 + 130147 = 130230
103 + 130127 = 130230

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 130,230 and was likely granted around 1872.

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