Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170208, here are decompositions:

11 + 170197 = 170208
19 + 170189 = 170208
29 + 170179 = 170208
41 + 170167 = 170208
67 + 170141 = 170208
97 + 170111 = 170208
107 + 170101 = 170208
109 + 170099 = 170208

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 170,208 and was likely granted around 1874.

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