Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165108, here are decompositions:
- 5 + 165103 = 165108
- 19 + 165089 = 165108
- 29 + 165079 = 165108
- 59 + 165049 = 165108
- 61 + 165047 = 165108
- 67 + 165041 = 165108
- 71 + 165037 = 165108
- 107 + 165001 = 165108
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 165,108 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 165108 first appears in π at position 443,429 of the decimal expansion (the 443,429ordinal-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.
