Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169104, here are decompositions:
- 7 + 169097 = 169104
- 11 + 169093 = 169104
- 37 + 169067 = 169104
- 41 + 169063 = 169104
- 97 + 169007 = 169104
- 101 + 169003 = 169104
- 113 + 168991 = 169104
- 127 + 168977 = 169104
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 169,104 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 169104 first appears in π at position 70,911 of the decimal expansion (the 70,911ordinal-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.
