Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164136, here are decompositions:
- 19 + 164117 = 164136
- 23 + 164113 = 164136
- 43 + 164093 = 164136
- 47 + 164089 = 164136
- 79 + 164057 = 164136
- 97 + 164039 = 164136
- 113 + 164023 = 164136
- 139 + 163997 = 164136
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 164,136 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 164136 first appears in π at position 225,752 of the decimal expansion (the 225,752ordinal-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.
