Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164628, here are decompositions:
- 5 + 164623 = 164628
- 7 + 164621 = 164628
- 11 + 164617 = 164628
- 29 + 164599 = 164628
- 41 + 164587 = 164628
- 47 + 164581 = 164628
- 59 + 164569 = 164628
- 97 + 164531 = 164628
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 164,628 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 164628 first appears in π at position 360,194 of the decimal expansion (the 360,194ordinal-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.
