Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159800, here are decompositions:

7 + 159793 = 159800
13 + 159787 = 159800
31 + 159769 = 159800
37 + 159763 = 159800
61 + 159739 = 159800
79 + 159721 = 159800
103 + 159697 = 159800
127 + 159673 = 159800

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 159,800 and was likely granted around 1873.

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