Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108700, here are decompositions:

23 + 108677 = 108700
113 + 108587 = 108700
167 + 108533 = 108700
197 + 108503 = 108700
239 + 108461 = 108700
353 + 108347 = 108700
467 + 108233 = 108700
509 + 108191 = 108700

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 108,700 and was likely granted around 1871.

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