Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105982, here are decompositions:

5 + 105977 = 105982
11 + 105971 = 105982
29 + 105953 = 105982
53 + 105929 = 105982
83 + 105899 = 105982
281 + 105701 = 105982
419 + 105563 = 105982
449 + 105533 = 105982

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 105.982 and was likely granted around 1870.

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