Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105688, here are decompositions:

5 + 105683 = 105688
131 + 105557 = 105688
179 + 105509 = 105688
197 + 105491 = 105688
239 + 105449 = 105688
251 + 105437 = 105688
281 + 105407 = 105688
347 + 105341 = 105688

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 105,688 and was likely granted around 1870.

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