Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170170, here are decompositions:

3 + 170167 = 170170
29 + 170141 = 170170
47 + 170123 = 170170
59 + 170111 = 170170
71 + 170099 = 170170
89 + 170081 = 170170
107 + 170063 = 170170
113 + 170057 = 170170

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 170,170 and was likely granted around 1874.

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