Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179940, here are decompositions:

17 + 179923 = 179940
23 + 179917 = 179940
31 + 179909 = 179940
37 + 179903 = 179940
41 + 179899 = 179940
43 + 179897 = 179940
107 + 179833 = 179940
113 + 179827 = 179940

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 179,940 and was likely granted around 1875.

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