Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100470, here are decompositions:

11 + 100459 = 100470
23 + 100447 = 100470
53 + 100417 = 100470
59 + 100411 = 100470
67 + 100403 = 100470
79 + 100391 = 100470
107 + 100363 = 100470
109 + 100361 = 100470

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 100,470 and was likely granted around 1870.

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