Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164560, here are decompositions:
- 29 + 164531 = 164560
- 47 + 164513 = 164560
- 83 + 164477 = 164560
- 89 + 164471 = 164560
- 113 + 164447 = 164560
- 131 + 164429 = 164560
- 173 + 164387 = 164560
- 197 + 164363 = 164560
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 164,560 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 164560 first appears in π at position 86,160 of the decimal expansion (the 86,160ordinal-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.
