Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163600, here are decompositions:

83 + 163517 = 163600
113 + 163487 = 163600
131 + 163469 = 163600
167 + 163433 = 163600
191 + 163409 = 163600
197 + 163403 = 163600
233 + 163367 = 163600
263 + 163337 = 163600

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 163,600 and was likely granted around 1874.

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