Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160900, here are decompositions:

17 + 160883 = 160900
23 + 160877 = 160900
59 + 160841 = 160900
71 + 160829 = 160900
83 + 160817 = 160900
149 + 160751 = 160900
191 + 160709 = 160900
251 + 160649 = 160900

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 160,900 and was likely granted around 1874.

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