Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164620, here are decompositions:
- 3 + 164617 = 164620
- 89 + 164531 = 164620
- 107 + 164513 = 164620
- 149 + 164471 = 164620
- 173 + 164447 = 164620
- 191 + 164429 = 164620
- 233 + 164387 = 164620
- 257 + 164363 = 164620
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 164,620 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 164620 first appears in π at position 906,032 of the decimal expansion (the 906,032ordinal-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.
