Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105130, here are decompositions:

23 + 105107 = 105130
59 + 105071 = 105130
107 + 105023 = 105130
131 + 104999 = 105130
197 + 104933 = 105130
239 + 104891 = 105130
251 + 104879 = 105130
281 + 104849 = 105130

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 105 130 and was likely granted around 1870.

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