Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173000, here are decompositions:

7 + 172993 = 173000
13 + 172987 = 173000
19 + 172981 = 173000
31 + 172969 = 173000
67 + 172933 = 173000
151 + 172849 = 173000
193 + 172807 = 173000
199 + 172801 = 173000

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 173,000 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 173000 first appears in π at position 162,533 of the decimal expansion (the 162,533ordinal-suffix:rd 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.
