Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143164, here are decompositions:
- 5 + 143159 = 143164
- 23 + 143141 = 143164
- 53 + 143111 = 143164
- 71 + 143093 = 143164
- 101 + 143063 = 143164
- 191 + 142973 = 143164
- 257 + 142907 = 143164
- 293 + 142871 = 143164
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 143,164 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 143164 first appears in π at position 815,310 of the decimal expansion (the 815,310ordinal-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.
