Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163604, here are decompositions:
- 3 + 163601 = 163604
- 31 + 163573 = 163604
- 37 + 163567 = 163604
- 43 + 163561 = 163604
- 61 + 163543 = 163604
- 127 + 163477 = 163604
- 193 + 163411 = 163604
- 211 + 163393 = 163604
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 163,604 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 163604 first appears in π at position 173,130 of the decimal expansion (the 173,130ordinal-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.
