Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164648, here are decompositions:
- 31 + 164617 = 164648
- 61 + 164587 = 164648
- 67 + 164581 = 164648
- 79 + 164569 = 164648
- 199 + 164449 = 164648
- 229 + 164419 = 164648
- 271 + 164377 = 164648
- 277 + 164371 = 164648
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 164,648 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 164648 first appears in π at position 206,002 of the decimal expansion (the 206,002ordinal-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.
