Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161364, here are decompositions:
- 23 + 161341 = 161364
- 31 + 161333 = 161364
- 41 + 161323 = 161364
- 61 + 161303 = 161364
- 83 + 161281 = 161364
- 97 + 161267 = 161364
- 101 + 161263 = 161364
- 127 + 161237 = 161364
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 161,364 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 161364 first appears in π at position 669,739 of the decimal expansion (the 669,739ordinal-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.
