Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100824, here are decompositions:

13 + 100811 = 100824
23 + 100801 = 100824
37 + 100787 = 100824
83 + 100741 = 100824
131 + 100693 = 100824
151 + 100673 = 100824
211 + 100613 = 100824
233 + 100591 = 100824

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 100,824 and was likely granted around 1870.

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