Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169906, here are decompositions:

17 + 169889 = 169906
47 + 169859 = 169906
83 + 169823 = 169906
89 + 169817 = 169906
137 + 169769 = 169906
173 + 169733 = 169906
197 + 169709 = 169906
239 + 169667 = 169906

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 169,906 and was likely granted around 1874.

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