Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164894, here are decompositions:
- 13 + 164881 = 164894
- 73 + 164821 = 164894
- 127 + 164767 = 164894
- 151 + 164743 = 164894
- 193 + 164701 = 164894
- 211 + 164683 = 164894
- 241 + 164653 = 164894
- 271 + 164623 = 164894
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 164,894 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 164894 first appears in π at position 400,139 of the decimal expansion (the 400,139ordinal-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.
