Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166000, here are decompositions:

17 + 165983 = 166000
53 + 165947 = 166000
59 + 165941 = 166000
113 + 165887 = 166000
167 + 165833 = 166000
251 + 165749 = 166000
281 + 165719 = 166000
293 + 165707 = 166000

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 166,000 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 166000 first appears in π at position 635,414 of the decimal expansion (the 635,414ordinal-suffix:th 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.
