Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168604, here are decompositions:
- 3 + 168601 = 168604
- 5 + 168599 = 168604
- 71 + 168533 = 168604
- 113 + 168491 = 168604
- 251 + 168353 = 168604
- 257 + 168347 = 168604
- 281 + 168323 = 168604
- 311 + 168293 = 168604
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 168,604 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 168604 first appears in π at position 401,811 of the decimal expansion (the 401,811ordinal-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.
