Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165464, here are decompositions:
- 7 + 165457 = 165464
- 67 + 165397 = 165464
- 73 + 165391 = 165464
- 97 + 165367 = 165464
- 151 + 165313 = 165464
- 283 + 165181 = 165464
- 331 + 165133 = 165464
- 463 + 165001 = 165464
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 165,464 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 165464 first appears in π at position 56,162 of the decimal expansion (the 56,162ordinal-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.
