Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160830, here are decompositions:

13 + 160817 = 160830
17 + 160813 = 160830
23 + 160807 = 160830
41 + 160789 = 160830
73 + 160757 = 160830
79 + 160751 = 160830
107 + 160723 = 160830
149 + 160681 = 160830

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 160,830 and was likely granted around 1873.

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