Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105238, here are decompositions:

11 + 105227 = 105238
71 + 105167 = 105238
101 + 105137 = 105238
131 + 105107 = 105238
167 + 105071 = 105238
239 + 104999 = 105238
251 + 104987 = 105238
347 + 104891 = 105238

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 105.238 and was likely granted around 1870.

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