Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100690, here are decompositions:

17 + 100673 = 100690
41 + 100649 = 100690
131 + 100559 = 100690
167 + 100523 = 100690
173 + 100517 = 100690
179 + 100511 = 100690
197 + 100493 = 100690
311 + 100379 = 100690

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 100,690 and was likely granted around 1870.

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