Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100680, here are decompositions:

7 + 100673 = 100680
11 + 100669 = 100680
31 + 100649 = 100680
59 + 100621 = 100680
67 + 100613 = 100680
71 + 100609 = 100680
89 + 100591 = 100680
131 + 100549 = 100680

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 100,680 and was likely granted around 1870.

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