Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100492, here are decompositions:

23 + 100469 = 100492
89 + 100403 = 100492
101 + 100391 = 100492
113 + 100379 = 100492
131 + 100361 = 100492
149 + 100343 = 100492
179 + 100313 = 100492
383 + 100109 = 100492

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 100,492 and was likely granted around 1870.

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