Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164578, here are decompositions:
- 47 + 164531 = 164578
- 101 + 164477 = 164578
- 107 + 164471 = 164578
- 131 + 164447 = 164578
- 149 + 164429 = 164578
- 191 + 164387 = 164578
- 257 + 164321 = 164578
- 269 + 164309 = 164578
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 164,578 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 164578 first appears in π at position 712,481 of the decimal expansion (the 712,481ordinal-suffix:st 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.
