Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164180, here are decompositions:
- 7 + 164173 = 164180
- 31 + 164149 = 164180
- 67 + 164113 = 164180
- 109 + 164071 = 164180
- 157 + 164023 = 164180
- 193 + 163987 = 164180
- 199 + 163981 = 164180
- 271 + 163909 = 164180
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 164,180 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 164180 first appears in π at position 274,722 of the decimal expansion (the 274,722ordinal-suffix:nd 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.
