Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154164, here are decompositions:
- 5 + 154159 = 154164
- 7 + 154157 = 154164
- 11 + 154153 = 154164
- 37 + 154127 = 154164
- 53 + 154111 = 154164
- 67 + 154097 = 154164
- 83 + 154081 = 154164
- 97 + 154067 = 154164
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 154,164 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 154164 first appears in π at position 277,562 of the decimal expansion (the 277,562ordinal-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.
