Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100530, here are decompositions:

7 + 100523 = 100530
11 + 100519 = 100530
13 + 100517 = 100530
19 + 100511 = 100530
29 + 100501 = 100530
37 + 100493 = 100530
47 + 100483 = 100530
61 + 100469 = 100530

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 100,530 and was likely granted around 1870.

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