Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165424, here are decompositions:
- 41 + 165383 = 165424
- 107 + 165317 = 165424
- 113 + 165311 = 165424
- 131 + 165293 = 165424
- 137 + 165287 = 165424
- 191 + 165233 = 165424
- 251 + 165173 = 165424
- 263 + 165161 = 165424
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 165,424 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 165424 first appears in π at position 120,696 of the decimal expansion (the 120,696ordinal-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.
