Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164630, here are decompositions:
- 3 + 164627 = 164630
- 7 + 164623 = 164630
- 13 + 164617 = 164630
- 31 + 164599 = 164630
- 43 + 164587 = 164630
- 61 + 164569 = 164630
- 127 + 164503 = 164630
- 181 + 164449 = 164630
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 164,630 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 164630 first appears in π at position 985,393 of the decimal expansion (the 985,393ordinal-suffix:rd 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.
