Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164870, here are decompositions:
- 31 + 164839 = 164870
- 61 + 164809 = 164870
- 103 + 164767 = 164870
- 127 + 164743 = 164870
- 163 + 164707 = 164870
- 193 + 164677 = 164870
- 271 + 164599 = 164870
- 283 + 164587 = 164870
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 164,870 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 164870 first appears in π at position 109,049 of the decimal expansion (the 109,049ordinal-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.
