Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165404, here are decompositions:
- 7 + 165397 = 165404
- 13 + 165391 = 165404
- 37 + 165367 = 165404
- 61 + 165343 = 165404
- 73 + 165331 = 165404
- 157 + 165247 = 165404
- 193 + 165211 = 165404
- 223 + 165181 = 165404
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 165,404 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 165404 first appears in π at position 292,913 of the decimal expansion (the 292,913ordinal-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.
