Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181710, here are decompositions:

17 + 181693 = 181710
41 + 181669 = 181710
43 + 181667 = 181710
71 + 181639 = 181710
101 + 181609 = 181710
103 + 181607 = 181710
107 + 181603 = 181710
157 + 181553 = 181710

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 181,710 and was likely granted around 1875.

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