Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164970, here are decompositions:
- 7 + 164963 = 164970
- 17 + 164953 = 164970
- 59 + 164911 = 164970
- 89 + 164881 = 164970
- 131 + 164839 = 164970
- 139 + 164831 = 164970
- 149 + 164821 = 164970
- 181 + 164789 = 164970
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 164,970 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 164970 first appears in π at position 93,168 of the decimal expansion (the 93,168ordinal-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.
