Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100486, here are decompositions:

3 + 100483 = 100486
17 + 100469 = 100486
83 + 100403 = 100486
107 + 100379 = 100486
173 + 100313 = 100486
293 + 100193 = 100486
317 + 100169 = 100486
383 + 100103 = 100486

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 100,486 and was likely granted around 1870.

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