Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164700, here are decompositions:
- 17 + 164683 = 164700
- 23 + 164677 = 164700
- 37 + 164663 = 164700
- 47 + 164653 = 164700
- 73 + 164627 = 164700
- 79 + 164621 = 164700
- 83 + 164617 = 164700
- 101 + 164599 = 164700
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 164,700 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 164700 first appears in π at position 79,062 of the decimal expansion (the 79,062ordinal-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.
