Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164390, here are decompositions:
- 3 + 164387 = 164390
- 13 + 164377 = 164390
- 19 + 164371 = 164390
- 139 + 164251 = 164390
- 151 + 164239 = 164390
- 157 + 164233 = 164390
- 181 + 164209 = 164390
- 199 + 164191 = 164390
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 164,390 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 164390 first appears in π at position 169,596 of the decimal expansion (the 169,596ordinal-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.
