Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164004, here are decompositions:
- 7 + 163997 = 164004
- 11 + 163993 = 164004
- 13 + 163991 = 164004
- 17 + 163987 = 164004
- 23 + 163981 = 164004
- 31 + 163973 = 164004
- 103 + 163901 = 164004
- 151 + 163853 = 164004
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 164,004 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 164004 first appears in π at position 204,222 of the decimal expansion (the 204,222ordinal-suffix:nd 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.
