Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165764, here are decompositions:
- 43 + 165721 = 165764
- 61 + 165703 = 165764
- 97 + 165667 = 165764
- 163 + 165601 = 165764
- 211 + 165553 = 165764
- 223 + 165541 = 165764
- 241 + 165523 = 165764
- 307 + 165457 = 165764
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 165,764 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 165764 first appears in π at position 192,113 of the decimal expansion (the 192,113ordinal-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.
