Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161324, here are decompositions:
- 43 + 161281 = 161324
- 61 + 161263 = 161324
- 103 + 161221 = 161324
- 157 + 161167 = 161324
- 271 + 161053 = 161324
- 277 + 161047 = 161324
- 307 + 161017 = 161324
- 421 + 160903 = 161324
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 161,324 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 161324 first appears in π at position 179,223 of the decimal expansion (the 179,223ordinal-suffix:rd 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.
