Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188030, here are decompositions:

13 + 188017 = 188030
19 + 188011 = 188030
43 + 187987 = 188030
67 + 187963 = 188030
79 + 187951 = 188030
103 + 187927 = 188030
109 + 187921 = 188030
331 + 187699 = 188030

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 188,030 and was likely granted around 1875.

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