Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101886, here are decompositions:

7 + 101879 = 101886
13 + 101873 = 101886
17 + 101869 = 101886
23 + 101863 = 101886
47 + 101839 = 101886
53 + 101833 = 101886
79 + 101807 = 101886
89 + 101797 = 101886

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 101,886 and was likely granted around 1870.

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