Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170910, here are decompositions:

11 + 170899 = 170910
23 + 170887 = 170910
29 + 170881 = 170910
37 + 170873 = 170910
53 + 170857 = 170910
59 + 170851 = 170910
67 + 170843 = 170910
73 + 170837 = 170910

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 170,910 and was likely granted around 1874.

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