Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164138, here are decompositions:
- 67 + 164071 = 164138
- 127 + 164011 = 164138
- 151 + 163987 = 164138
- 157 + 163981 = 164138
- 211 + 163927 = 164138
- 229 + 163909 = 164138
- 277 + 163861 = 164138
- 349 + 163789 = 164138
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 164,138 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 164138 first appears in π at position 826,006 of the decimal expansion (the 826,006ordinal-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.
