Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164590, here are decompositions:
- 3 + 164587 = 164590
- 59 + 164531 = 164590
- 113 + 164477 = 164590
- 227 + 164363 = 164590
- 233 + 164357 = 164590
- 269 + 164321 = 164590
- 281 + 164309 = 164590
- 311 + 164279 = 164590
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 164,590 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 164590 first appears in π at position 480,987 of the decimal expansion (the 480,987ordinal-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.
