Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161304, here are decompositions:
- 23 + 161281 = 161304
- 37 + 161267 = 161304
- 41 + 161263 = 161304
- 67 + 161237 = 161304
- 71 + 161233 = 161304
- 83 + 161221 = 161304
- 103 + 161201 = 161304
- 137 + 161167 = 161304
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 161,304 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 161304 first appears in π at position 389,004 of the decimal expansion (the 389,004ordinal-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.
