Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164678, here are decompositions:
- 61 + 164617 = 164678
- 79 + 164599 = 164678
- 97 + 164581 = 164678
- 109 + 164569 = 164678
- 229 + 164449 = 164678
- 307 + 164371 = 164678
- 337 + 164341 = 164678
- 379 + 164299 = 164678
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 164,678 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 164678 first appears in π at position 523,036 of the decimal expansion (the 523,036ordinal-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.
