Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159100, here are decompositions:

3 + 159097 = 159100
41 + 159059 = 159100
83 + 159017 = 159100
107 + 158993 = 159100
173 + 158927 = 159100
191 + 158909 = 159100
233 + 158867 = 159100
251 + 158849 = 159100

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 159,100 and was likely granted around 1873.

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