Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170000, here are decompositions:

13 + 169987 = 170000
43 + 169957 = 170000
67 + 169933 = 170000
109 + 169891 = 170000
157 + 169843 = 170000
163 + 169837 = 170000
211 + 169789 = 170000
223 + 169777 = 170000

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 170,000 and was likely granted around 1874.

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

Position in π

The digit sequence 170000 first appears in π at position 855,242 of the decimal expansion (the 855,242ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
