Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165252, here are decompositions:
- 5 + 165247 = 165252
- 19 + 165233 = 165252
- 23 + 165229 = 165252
- 41 + 165211 = 165252
- 71 + 165181 = 165252
- 79 + 165173 = 165252
- 149 + 165103 = 165252
- 163 + 165089 = 165252
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 165,252 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 165252 first appears in π at position 231,536 of the decimal expansion (the 231,536ordinal-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.
